     * \@description
     * A {\@link LocationStrategy} used to configure the {\@link Location} service to
     * represent its state in the
     * [path](https://en.wikipedia.org/wiki/Uniform_Resource_Locator#Syntax) of the
     * browser's URL.
     *
     * If you're using `PathLocationStrategy`, you must provide a {\@link APP_BASE_HREF}
     * or add a base element to the document. This URL prefix that will be preserved
     * when generating and recognizing URLs.
     *
     * For instance, if you provide an `APP_BASE_HREF` of `'/my/app'` and call
     * `location.go('/foo')`, the browser's URL will become
     * `example.com/my/app/foo`.
     *
     * Similarly, if you add `<base href='/my/app'/>` to the document and call
     * `location.go('/foo')`, the browser's URL will become
     * `example.com/my/app/foo`.

    /**
     * Used to diff and convert ngStyle/ngClass instructions into [style] and [class] bindings.
     *
     * ngStyle and ngClass both accept various forms of input and behave differently than that
     * of how [style] and [class] behave in Angular.
     *
     * The differences are:
     *  - ngStyle and ngClass both **watch** their binding values for changes each time CD runs
     *    while [style] and [class] bindings do not (they check for identity changes)
     *  - ngStyle allows for unit-based keys (e.g. `{'max-width.px':value}`) and [style] does not
     *  - ngClass supports arrays of class values and [class] only accepts map and string values
     *  - ngClass allows for multiple className keys (space-separated) within an array or map
     *     (as the * key) while [class] only accepts a simple key/value map object
     *
     * Having Angular understand and adapt to all the different forms of behavior is complicated
     * and unnecessary. Instead, ngClass and ngStyle should have their input values be converted
     * into something that the core-level [style] and [class] bindings understand.
     *
     * This [StylingDiffer] class handles this conversion by creating a new input value each time
     * the inner representation of the binding value have changed.
     *
     * ## Why do we care about ngStyle/ngClass?
     * The styling algorithm code (documented inside of `render3/interfaces/styling.ts`) needs to
     * respect and understand the styling values emitted through ngStyle and ngClass (when they
     * are present and used in a template).
     *
     * Instead of having these directives manage styling on their own, they should be included
     * into the Angular styling algorithm that exists for [style] and [class] bindings.
     *
     * Here's why:
     *
     * - If ngStyle/ngClass is used in combination with [style]/[class] bindings then the
     *   styles and classes would fall out of sync and be applied and updated at
     *   inconsistent times
     * - Both ngClass/ngStyle do not respect [class.name] and [style.prop] bindings
     *   (they will write over them given the right combination of events)
     *
     *   ```
     *   <!-- if `w1` is updated then it will always override `w2`
     *        if `w2` is updated then it will always override `w1`
     *        if both are updated at the same time then `w1` wins -->
     *   <div [ngStyle]="{width:w1}" [style.width]="w2">...</div>
     *
     *   <!-- if `w1` is updated then it will always lose to `w2`
     *        if `w2` is updated then it will always override `w1`
     *        if both are updated at the same time then `w2` wins -->
     *   <div [style]="{width:w1}" [style.width]="w2">...</div>
     *   ```
     * - ngClass/ngStyle were written as a directives and made use of maps, closures and other
     *   expensive data structures which were evaluated each time CD runs
     * @template T

     *
     * Simple
     * ```
     * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>

    /**
     * A [structural directive](guide/structural-directives) that renders
     * a template for each item in a collection.
     * The directive is placed on an element, which becomes the parent
     * of the cloned templates.
     *
     * The `ngForOf` directive is generally used in the
     * [shorthand form](guide/structural-directives#the-asterisk--prefix) `*ngFor`.
     * In this form, the template to be rendered for each iteration is the content
     * of an anchor element containing the directive.
     *
     * The following example shows the shorthand syntax with some options,
     * contained in an `<li>` element.
     *
     * ```
     * <li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>
     * ```
     *
     * The shorthand form expands into a long form that uses the `ngForOf` selector
     * on an `<ng-template>` element.
     * The content of the `<ng-template>` element is the `<li>` element that held the
     * short-form directive.
     *
     * Here is the expanded version of the short-form example.
     *
     * ```
     * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
     *   <li>...</li>
     * </ng-template>
     * ```
     *
     * Angular automatically expands the shorthand syntax as it compiles the template.
     * The context for each embedded view is logically merged to the current component
     * context according to its lexical position.
     *
     * When using the shorthand syntax, Angular allows only [one structural directive
     * on an element](guide/structural-directives#one-structural-directive-per-host-element).
     * If you want to iterate conditionally, for example,
     * put the `*ngIf` on a container element that wraps the `*ngFor` element.
     * For futher discussion, see
     * [Structural Directives](guide/structural-directives#one-per-element).
     *
     * \@usageNotes
     *
     * ### Local variables
     *
     * `NgForOf` provides exported values that can be aliased to local variables.
     * For example:
     *
     *  ```
     * <li *ngFor="let user of userObservable | async as users; index as i; first as isFirst">
     *    {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
     * </li>
     * ```
     *
     * The following exported values can be aliased to local variables:
     *
     * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
     * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
     * more complex then a property access, for example when using the async pipe (`userStreams |
     * async`).
     * - `index: number`: The index of the current item in the iterable.
     * - `first: boolean`: True when the item is the first item in the iterable.
     * - `last: boolean`: True when the item is the last item in the iterable.
     * - `even: boolean`: True when the item has an even index in the iterable.
     * - `odd: boolean`: True when the item has an odd index in the iterable.
     *
     * ### Change propagation
     *
     * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
     *
     * * When an item is added, a new instance of the template is added to the DOM.
     * * When an item is removed, its template instance is removed from the DOM.
     * * When items are reordered, their respective templates are reordered in the DOM.
     *
     * Angular uses object identity to track insertions and deletions within the iterator and reproduce
     * those changes in the DOM. This has important implications for animations and any stateful
     * controls that are present, such as `<input>` elements that accept user input. Inserted rows can
     * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
     * such as user input.
     * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).
     *
     * The identities of elements in the iterator can change while the data does not.
     * This can happen, for example, if the iterator is produced from an RPC to the server, and that
     * RPC is re-run. Even if the data hasn't changed, the second response produces objects with
     * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old
     * elements were deleted and all new elements inserted).
     *
     * To avoid this expensive operation, you can customize the default tracking algorithm.
     * by supplying the `trackBy` option to `NgForOf`.
     * `trackBy` takes a function that has two arguments: `index` and `item`.
     * If `trackBy` is given, Angular tracks changes by the return value of the function.

     * A structural directive that conditionally includes a template based on the value of
     * an expression coerced to Boolean.
     * When the expression evaluates to true, Angular renders the template
     * provided in a `then` clause, and when  false or null,
     * Angular renders the template provided in an optional `else` clause. The default
     * template for the `else` clause is blank.
     *
     * A [shorthand form](guide/structural-directives#the-asterisk--prefix) of the directive,
     * `*ngIf="condition"`, is generally used, provided
     * as an attribute of the anchor element for the inserted template.
     * Angular expands this into a more explicit version, in which the anchor element
     * is contained in an `<ng-template>` element.
     *
     * Simple form with shorthand syntax:
     *
     * ```
     * <div *ngIf="condition">Content to render when condition is true.</div>
     * ```
     *
     * Simple form with expanded syntax:

     * ```
     * <ng-template [ngIf]="condition"><div>Content to render when condition is
     * true.</div></ng-template>
     * ```
     *
     * Form with an "else" block:
     *
     * ```
     * <div *ngIf="condition; else elseBlock">Content to render when condition is true.</div>
     * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
     * ```
     *
     * Shorthand form with "then" and "else" blocks:
     *
     * ```
     * <div *ngIf="condition; then thenBlock else elseBlock"></div>
     * <ng-template #thenBlock>Content to render when condition is true.</ng-template>
     * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
     * ```
     *
     * Form with storing the value locally:
     *
     * ```
     * <div *ngIf="condition as value; else elseBlock">{{value}}</div>
     * <ng-template #elseBlock>Content to render when value is null.</ng-template>
     * ```
     *
     * \@usageNotes
     *
     * The `*ngIf` directive is most commonly used to conditionally show an inline template,
     * as seen in the following  example.
     * The default `else` template is blank.
     *
     * {\@example common/ngIf/ts/module.ts region='NgIfSimple'}
     *
     * ### Showing an alternative template using `else`
     *
     * To display a template when `expression` evaluates to false, use an `else` template
     * binding as shown in the following example.
     * The `else` binding points to an `<ng-template>`  element labeled `#elseBlock`.
     * The template can be defined anywhere in the component view, but is typically placed right after
     * `ngIf` for readability.
     *
     * {\@example common/ngIf/ts/module.ts region='NgIfElse'}
     *
     * ### Using an external `then` template
     *
     * In the previous example, the then-clause template is specified inline, as the content of the
     * tag that contains the `ngIf` directive. You can also specify a template that is defined
     * externally, by referencing a labeled `<ng-template>` element. When you do this, you can
     * change which template to use at runtime, as shown in the following example.
     *
     * {\@example common/ngIf/ts/module.ts region='NgIfThenElse'}
     *
     * ### Storing a conditional result in a variable
     *
     * You might want to show a set of properties from the same object. If you are waiting
     * for asynchronous data, the object can be undefined.
     * In this case, you can use `ngIf` and store the result of the condition in a local
     * variable as shown in the the following example.
     *
     * {\@example common/ngIf/ts/module.ts region='NgIfAs'}
     *
     * This code uses only one `AsyncPipe`, so only one subscription is created.
     * The conditional statement stores the result of `userStream|async` in the local variable `user`.
     * You can then bind the local `user` repeatedly.
     *
     * The conditional displays the data only if `userStream` returns a value,
     * so you don't need to use the
     * [safe-navigation-operator](guide/template-syntax#safe-navigation-operator) (`?.`)
     * to guard against null values when accessing properties.
     * You can display an alternative template while waiting for the data.
     *
     * ### Shorthand syntax
     *
     * The shorthand syntax `*ngIf` expands into two separate template specifications
     * for the "then" and "else" clauses. For example, consider the following shorthand statement,
     * that is meant to show a loading page while waiting for data to be loaded.
     *
     * ```
     * <div class="hero-list" *ngIf="heroes else loading">
     *  ...
     * </div>
     *
     * <ng-template #loading>
     *  <div>Loading...</div>
     * </ng-template>
     * ```
     *
     * You can see that the "else" clause references the `<ng-template>`
     * with the `#loading` label, and the template for the "then" clause
     * is provided as the content of the anchor element.
     *
     * However, when Angular expands the shorthand syntax, it creates
     * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.
     * The anchor element containing the template for the "then" clause becomes
     * the content of this unlabeled `<ng-template>` tag.
     *
     * ```
     * <ng-template [ngIf]="hero-list" [ngIfElse]="loading">
     *  <div class="hero-list">
     *   ...
     *  </div>
     * </ng-template>
     *
     * <ng-template #loading>
     *  <div>Loading...</div>
     * </ng-template>
     * ```
     *
     * The presence of the implicit template object has implications for the nesting of
     * structural directives. For more on this subject, see
     * [Structural Directives](https://angular.io/guide/structural-directives#one-per-element).

     * \@description A structural directive that adds or removes templates (displaying or hiding views)
     * when the next match expression matches the switch expression.
     *
     * The `[ngSwitch]` directive on a container specifies an expression to match against.
     * The expressions to match are provided by `ngSwitchCase` directives on views within the container.
     * - Every view that matches is rendered.
     * - If there are no matches, a view with the `ngSwitchDefault` directive is rendered.
     * - Elements within the `[NgSwitch]` statement but outside of any `NgSwitchCase`
     * or `ngSwitchDefault` directive are preserved at the location.
     *
     * \@usageNotes
     * Define a container element for the directive, and specify the switch expression
     * to match against as an attribute:
     *
     * ```
     * <container-element [ngSwitch]="switch_expression">
     * ```
     *
     * Within the container, `*ngSwitchCase` statements specify the match expressions
     * as attributes. Include `*ngSwitchDefault` as the final case.
     *
     * ```
     * <container-element [ngSwitch]="switch_expression">

     *    <some-element *ngSwitchDefault>...</some-element>
     * </container-element>
     * ```
     *
     * ### Usage Examples
     *
     * The following example shows how to use more than one case to display the same view:
     *
     * ```
     * <container-element [ngSwitch]="switch_expression">
     *   <!-- the same view can be shown in more than one case -->
     *   <some-element *ngSwitchCase="match_expression_1">...</some-element>
     *   <some-element *ngSwitchCase="match_expression_2">...</some-element>
     *   <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
     *   <!--default case when there are no matches -->
     *   <some-element *ngSwitchDefault>...</some-element>
     * </container-element>
     * ```
     *
     * The following example shows how cases can be nested:
     * ```
     * <container-element [ngSwitch]="switch_expression">
     *       <some-element *ngSwitchCase="match_expression_1">...</some-element>
     *       <some-element *ngSwitchCase="match_expression_2">...</some-element>
     *       <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
     *       <ng-container *ngSwitchCase="match_expression_3">
     *         <!-- use a ng-container to group multiple root nodes -->
     *         <inner-element></inner-element>
     *         <inner-other-element></inner-other-element>

     * WARNINGS:
     * - this pipe is marked as pure hence it will not be re-evaluated when the input is mutated.
     *   Instead users should treat the date as an immutable object and change the reference when the
     *   pipe needs to re-run (this is to avoid reformatting the date on every change detection run
     *   which would be an expensive operation).
     * - this pipe uses the Internationalization API. Therefore it is only reliable in Chrome and Opera
     *   browsers.

     * Unwraps a value from an asynchronous primitive.
     *
     * The `async` pipe subscribes to an `Observable` or `Promise` and returns the latest value it has
     * emitted. When a new value is emitted, the `async` pipe marks the component to be checked for
     * changes. When the component gets destroyed, the `async` pipe unsubscribes automatically to avoid
     * potential memory leaks.
     *
     * \@usageNotes
     *
     * ### Examples
     *
     * This example binds a `Promise` to the view. Clicking the `Resolve` button resolves the
     * promise.
     *
     * {\@example common/pipes/ts/async_pipe.ts region='AsyncPipePromise'}
     *
     * It's also possible to use `async` with Observables. The example below binds the `time` Observable
     * to the view. The Observable continuously updates the view with the current time.
     *
     * {\@example common/pipes/ts/async_pipe.ts region='AsyncPipeObservable'}

     * Formats a date value according to locale rules.
     *
     * Only the `en-US` locale data comes with Angular. To localize dates
     * in another language, you must import the corresponding locale data.
     * See the [I18n guide](guide/i18n#i18n-pipes) for more information.

     *
     * \@usageNotes
     *
     * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to
     * reformat the date on every change-detection cycle, treat the date as an immutable object
     * and change the reference when the pipe needs to run again.
     *
     * ### Pre-defined format options
     *
     * Examples are given in `en-US` locale.
     *
     * - `'short'`: equivalent to `'M/d/yy, h:mm a'` (`6/15/15, 9:03 AM`).
     * - `'medium'`: equivalent to `'MMM d, y, h:mm:ss a'` (`Jun 15, 2015, 9:03:01 AM`).
     * - `'long'`: equivalent to `'MMMM d, y, h:mm:ss a z'` (`June 15, 2015 at 9:03:01 AM
     * GMT+1`).
     * - `'full'`: equivalent to `'EEEE, MMMM d, y, h:mm:ss a zzzz'` (`Monday, June 15, 2015 at
     * 9:03:01 AM GMT+01:00`).
     * - `'shortDate'`: equivalent to `'M/d/yy'` (`6/15/15`).
     * - `'mediumDate'`: equivalent to `'MMM d, y'` (`Jun 15, 2015`).
     * - `'longDate'`: equivalent to `'MMMM d, y'` (`June 15, 2015`).
     * - `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` (`Monday, June 15, 2015`).
     * - `'shortTime'`: equivalent to `'h:mm a'` (`9:03 AM`).
     * - `'mediumTime'`: equivalent to `'h:mm:ss a'` (`9:03:01 AM`).
     * - `'longTime'`: equivalent to `'h:mm:ss a z'` (`9:03:01 AM GMT+1`).
     * - `'fullTime'`: equivalent to `'h:mm:ss a zzzz'` (`9:03:01 AM GMT+01:00`).
     *
     * ### Custom format options
     *
     * You can construct a format string using symbols to specify the components
     * of a date-time value, as described in the following table.
     * Format details depend on the locale.
     * Fields marked with (*) are only available in the extra data set for the given locale.
     *

     * ### Format examples
     *
     * These examples transform a date into various formats,
     * assuming that `dateObj` is a JavaScript `Date` object for
     * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
     * given in the local time for the `en-US` locale.
     *
     * ```
     * {{ dateObj | date }}               // output is 'Jun 15, 2015'
     * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'
     * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'
     * {{ dateObj | date:'mm:ss' }}       // output is '43:11'
     * ```
     *
     * ### Usage example
     *
     * The following component uses a date pipe to display the current date in different formats.
     *
     * ```
     * \@Component({
     *  selector: 'date-pipe',
     *  template: `<div>
     *    <p>Today is {{today | date}}</p>
     *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>
     *    <p>The time is {{today | date:'h:mm a z'}}</p>
     *  </div>`
     * })
     * // Get the current date and time as a date-time value.
     * export class DatePipeComponent {
     *   today: number = Date.now();
     * }
     * ```
     *
     * \@publicApi

      /**

       *   - `symbol-narrow`: Use the narrow symbol for locales that have two symbols for their
       * currency.
       * For example, the Canadian dollar CAD has the symbol `CA$` and the symbol-narrow `$`. If the
       * locale has no narrow symbol, uses the standard symbol for the locale.

       * in the following format:<br>
       * <code>{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}</code>.
       *   - `minIntegerDigits`: The minimum number of integer digits before the decimal point.
       * Default is `1`.
       *   - `minFractionDigits`: The minimum number of digits after the decimal point.
       * Default is `2`.
       *   - `maxFractionDigits`: The maximum number of digits after the decimal point.
       * Default is `2`.
       * If not provided, the number will be formatted with the proper amount of digits,
       * depending on what the [ISO 4217](https://en.wikipedia.org/wiki/ISO_4217) specifies.
       * For example, the Canadian dollar has 2 digits, whereas the Chilean peso has none.

      This is a limited shim for ShadowDOM css styling.
      https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#styles
    
      The intention here is to support only the styling features which can be
      relatively simply implemented. The goal is to allow users to avoid the
      most obvious pitfalls and do so without compromising performance significantly.
      For ShadowDOM styling that's not covered here, a set of best practices
      can be provided that should allow users to accomplish more complex styling.
    
      The following is a list of specific ShadowDOM styling features and a brief
      discussion of the approach used to shim.
    
      Shimmed features:
    
      * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host
      element using the :host rule. To shim this feature, the :host styles are
      reformatted and prefixed with a given scope name and promoted to a
      document level stylesheet.
      For example, given a scope name of .foo, a rule like this:
    
        :host {
            background: red;
          }
        }
    
      becomes:
    
        .foo {
          background: red;
        }
    
      * encapsulation: Styles defined within ShadowDOM, apply only to
      dom inside the ShadowDOM. Polymer uses one of two techniques to implement
      this feature.
    
      By default, rules are prefixed with the host element tag name
      as a descendant selector. This ensures styling does not leak out of the 'top'
      of the element's ShadowDOM. For example,
    
      div {
          font-weight: bold;
        }
    
      becomes:
    
      x-foo div {
          font-weight: bold;
        }
    
      becomes:
    
    
      Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then
      selectors are scoped by adding an attribute selector suffix to each
      simple selector that contains the host element tag name. Each element
      in the element's ShadowDOM template is also given the scope attribute.
      Thus, these rules match only elements that have the scope attribute.
      For example, given a scope name of x-foo, a rule like this:
    
        div {
          font-weight: bold;
        }
    
      becomes:
    
        div[x-foo] {
          font-weight: bold;
        }
    
      Note that elements that are dynamically added to a scope must have the scope
      selector added to them manually.
    
      * upper/lower bound encapsulation: Styles which are defined outside a
      shadowRoot should not cross the ShadowDOM boundary and should not apply
      inside a shadowRoot.
    
      This styling behavior is not emulated. Some possible ways to do this that
      were rejected due to complexity and/or performance concerns include: (1) reset
      every possible property for every possible selector for a given scope name;
      (2) re-implement css in javascript.
    
      As an alternative, users should make sure to use selectors
      specific to the scope in which they are working.
    
      * ::distributed: This behavior is not emulated. It's often not necessary
      to style the contents of a specific insertion point and instead, descendants
      of the host element can be styled selectively. Users can also create an
      extra node around an insertion point and style that node's contents
      via descendent selectors. For example, with a shadowRoot like this:
    
        <style>
          ::content(div) {
            background: red;
          }
        </style>
        <content></content>
    
      could become:
    
        <style>
          / *@polyfill .content-container div * /
          ::content(div) {
            background: red;
          }
        </style>
        <div class="content-container">
          <content></content>
        </div>
    
      Note the use of @polyfill in the comment above a ShadowDOM specific style
      declaration. This is a directive to the styling shim to use the selector
      in comments in lieu of the next selector when running under polyfill.

     * This array represents the DOM schema. It encodes inheritance, properties, and events.
     *
     * ## Overview
     *
     * Each line represents one kind of element. The `element_inheritance` and properties are joined
     * using `element_inheritance|properties` syntax.
     *
     * ## Element Inheritance
     *
     * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.
     * Here the individual elements are separated by `,` (commas). Every element in the list
     * has identical properties.
     *
     * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is
     * specified then `""` (blank) element is assumed.
     *
     * NOTE: The blank element inherits from root `[Element]` element, the super element of all
     * elements.
     *
     * NOTE an element prefix such as `:svg:` has no special meaning to the schema.
     *
     * ## Properties
     *
     * Each element has a set of properties separated by `,` (commas). Each property can be prefixed
     * by a special character designating its type:
     *
     * - (no prefix): property is a string.
     * - `*`: property represents an event.
     * - `!`: property is a boolean.
     * - `#`: property is a number.
     * - `%`: property is an object.
     *
     * ## Query
     *
     * The class creates an internal squas representation which allows to easily answer the query of
     * if a given property exist on a given element.
     *
     * NOTE: We don't yet support querying for types or events.
     * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,
     *       see dom_element_schema_registry_spec.ts

     * A regular expression for breaking a URI into its component parts.
     *
     * {@link http://www.gbiv.com/protocols/uri/rfc/rfc3986.html#RFC2234} says
     * As the "first-match-wins" algorithm is identical to the "greedy"
     * disambiguation method used by POSIX regular expressions, it is natural and
     * commonplace to use a regular expression for parsing the potential five
     * components of a URI reference.
     *
     * The following line is the regular expression for breaking-down a
     * well-formed URI reference into its components.
     *
     * <pre>
     * ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
     *  12            3  4          5       6  7        8 9
     * </pre>
     *
     * The numbers in the second line above are only to assist readability; they
     * indicate the reference points for each subexpression (i.e., each paired
     * parenthesis). We refer to the value matched for subexpression <n> as $<n>.
     * For example, matching the above expression to
     * <pre>
     *     http://www.ics.uci.edu/pub/ietf/uri/#Related
     * </pre>
     * results in the following subexpression matches:
     * <pre>
     *    $1 = http:
     *    $2 = http
     *    $3 = //www.ics.uci.edu
     *    $4 = www.ics.uci.edu
     *    $5 = /pub/ietf/uri/
     *    $6 = <undefined>
     *    $7 = <undefined>
     *    $8 = #Related
     *    $9 = Related
     * </pre>
     * where <undefined> indicates that the component is not present, as is the
     * case for the query component in the above example. Therefore, we can
     * determine the value of the five components as
     * <pre>
     *    scheme    = $2
     *    authority = $4
     *    path      = $5
     *    query     = $7
     *    fragment  = $9
     * </pre>
     *
     * The regular expression has been modified slightly to expose the
     * userInfo, domain, and port separately from the authority.
     * The modified version yields
     * <pre>
     *    $1 = http              scheme
     *    $2 = <undefined>       userInfo -\
     *    $3 = www.ics.uci.edu   domain     | authority
     *    $4 = <undefined>       port     -/

     * Creates a token that can be used in a DI Provider.
     *
     * Use an `InjectionToken` whenever the type you are injecting is not reified (does not have a
     * runtime representation) such as when injecting an interface, callable type, array or
     * parameterized type.
     *
     * `InjectionToken` is parameterized on `T` which is the type of object which will be returned by
     * the `Injector`. This provides additional level of type safety.
     *
     * ```
     * interface MyInterface {...}
     * var myInterface = injector.get(new InjectionToken<MyInterface>('SomeToken'));
     * // myInterface is inferred to be MyInterface.
     * ```
     *
     * When creating an `InjectionToken`, you can optionally specify a factory function which returns
     * (possibly by creating) a default value of the parameterized type `T`. This sets up the
     * `InjectionToken` using this factory as a provider as if it was defined explicitly in the
     * application's root injector. If the factory function, which takes zero arguments, needs to inject
     * dependencies, it can do so using the `inject` function. See below for an example.
     *
     * Additionally, if a `factory` is specified you can also specify the `providedIn` option, which
     * overrides the above behavior and marks the token as belonging to a particular `\@NgModule`. As
     * mentioned above, `'root'` is the default value for `providedIn`.

     * // TODO(matsko): add updateMask info
     *
     * This file contains all state-based logic for styling in Angular.
     *
     * Styling in Angular is evaluated with a series of styling-specific
     * template instructions which are called one after another each time
     * change detection occurs in Angular.
     *
     * Styling makes use of various temporary, state-based variables between
     * instructions so that it can better cache and optimize its values.
     * These values are usually populated and cleared when an element is
     * exited in change detection (once all the instructions are run for
     * that element).
     *
     * There are, however, situations where the state-based values
     * need to be stored and used at a later point. This ONLY occurs when
     * there are template-level as well as host-binding-level styling
     * instructions on the same element. The example below shows exactly
     * what could be:
     *
     * ```html
     * <!-- two sources of styling: the template and the directive -->
     * <div [style.width]="width" dir-that-sets-height></div>
     * ```
     *
     * If and when this situation occurs, the current styling state is
     * stored in a storage map value and then later accessed once the
     * host bindings are evaluated. Once styling for the current element
     * is over then the map entry will be cleared.
     *
     * To learn more about the algorithm see `TStylingContext`.
     *

     * This function is shared between bindings that are assigned immediately
     * (via `updateBindingData`) and at a deferred stage. When called, it will
     * figure out exactly where to place the binding data in the context.
     *
     * It is needed because it will either update or insert a styling property
     * into the context at the correct spot.
     *
     * When called, one of two things will happen:
     *
     * 1) If the property already exists in the context then it will just add
     *    the provided `bindingValue` to the end of the binding sources region
     *    for that particular property.
     *
     *    - If the binding value is a number then it will be added as a new
     *      binding index source next to the other binding sources for the property.
     *
     *    - Otherwise, if the binding value is a string/boolean/null type then it will
     *      replace the default value for the property if the default value is `null`.
     *
     * 2) If the property does not exist then it will be inserted into the context.
     *    The styling context relies on all properties being stored in alphabetical
     *    order, so it knows exactly where to store it.
     *
     *    When inserted, a default `null` value is created for the property which exists
     *    as the default value for the binding. If the bindingValue property is inserted
     *    and it is either a string, number or null value then that will replace the default
     *    value.
     *
     * Note that this function is also used for map-based styling bindings. They are treated
     * much the same as prop-based bindings, but, because they do not have a property value
     * (since it's a map), all map-based entries are stored in an already populated area of
     * the context at the top (which is reserved for map-based entries).

     *   so it can use these static styling values as defaults when a matching binding is falsy.

     *   provided `TStylingContext` (which is an instance of a `StylingMapArray`). This inner map will
     *   be updated each time a host binding applies its static styling values (via `elementHostAttrs`)
     *   so these values are only read at this point because this is the very last point before the

     * The basic idea is that `i18nExp` OpCodes capture expression changes and update a change
     * mask bit. (Bit 1 for expression 1, bit 2 for expression 2 etc..., bit 32 for expression 32 and
     * higher.) The OpCodes then compare its own change mask against the expression change mask to
     * determine if the OpCodes should execute.
     *
     * These OpCodes can be used by both the i18n block as well as ICU sub-block.
     *
     * ## Example
     *
     * Assume
     * ```ts
     *   if (rf & RenderFlags.Update) {
     *    i18nExp(bind(ctx.exp1)); // If changed set mask bit 1
     *    i18nExp(bind(ctx.exp2)); // If changed set mask bit 2
     *    i18nExp(bind(ctx.exp3)); // If changed set mask bit 3
     *    i18nExp(bind(ctx.exp4)); // If changed set mask bit 4
     *    i18nApply(0);            // Apply all changes by executing the OpCodes.
     *  }
     * ```
     * We can assume that each call to `i18nExp` sets an internal `changeMask` bit depending on the
     * index of `i18nExp`.
     *
     * ### OpCodes
     * ```ts
     * <I18nUpdateOpCodes>[

    /**
     * Used to apply styling values presently within any map-based bindings on an element.
     *
     * Angular supports map-based styling bindings which can be applied via the
     * `[style]` and `[class]` bindings which can be placed on any HTML element.
     * These bindings can work independently, together or alongside prop-based
     * styling bindings (e.g. `<div [style]="x" [style.width]="w">`).
     *
     * If a map-based styling binding is detected by the compiler, the following
     * AOT code is produced:
     *
     * ```typescript
     * styleMap(ctx.styles); // styles = {key:value}
     * classMap(ctx.classes); // classes = {key:value}|string
     * ```
     *
     * If and when either of the instructions above are evaluated, then the code
     * present in this file is included into the bundle. The mechanism used, to
     * activate support for map-based bindings at runtime is possible via the
     * `activeStylingMapFeature` function (which is also present in this file).
     *
     * # The Algorithm
     * Whenever a map-based binding updates (which is when the identity of the
     * map-value changes) then the map is iterated over and a `StylingMapArray` array
     * is produced. The `StylingMapArray` instance is stored in the binding location
     * where the `BINDING_INDEX` is situated when the `styleMap()` or `classMap()`
     * instruction were called. Once the binding changes, then the internal `bitMask`
     * value is marked as dirty.
     *
     * Styling values are applied once CD exits the element (which happens when
     * the `select(n)` instruction is called or the template function exits). When
     * this occurs, all prop-based bindings are applied. If a map-based binding is
     * present then a special flushing function (called a sync function) is made
     * available and it will be called each time a styling property is flushed.
     *
     * The flushing algorithm is designed to apply styling for a property (which is
     * a CSS property or a className value) one by one. If map-based bindings
     * are present, then the flushing algorithm will keep calling the maps styling
     * sync function each time a property is visited. This way, the flushing
     * behavior of map-based bindings will always be at the same property level
     * as the current prop-based property being iterated over (because everything
     * is alphabetically sorted).
     *
     * Let's imagine we have the following HTML template code:
     *
     * ```html
     * <div [style]="{width:'100px', height:'200px', 'z-index':'10'}"
     *      [style.width.px]="200">...</div>
     * ```
     *
     * When CD occurs, both the `[style]` and `[style.width]` bindings
     * are evaluated. Then when the styles are flushed on screen, the
     * following operations happen:
     *
     * 1. `[style.width]` is attempted to be written to the element.
     *
     * 2.  Once that happens, the algorithm instructs the map-based
     *     entries (`[style]` in this case) to "catch up" and apply
     *     all values up to the `width` value. When this happens the
     *     `height` value is applied to the element (since it is
     *     alphabetically situated before the `width` property).
     *
     * 3. Since there are no more prop-based entries anymore, the
     *    loop exits and then, just before the flushing ends, it
     *    instructs all map-based bindings to "finish up" applying
     *    their values.
     *
     * 4. The only remaining value within the map-based entries is
     *    the `z-index` value (`width` got skipped because it was
     *    successfully applied via the prop-based `[style.width]`
     *    binding). Since all map-based entries are told to "finish up",
     *    the `z-index` value is iterated over and it is then applied
     *    to the element.
     *
     * The most important thing to take note of here is that prop-based
     * bindings are evaluated in order alongside map-based bindings.
     * This allows all styling across an element to be applied in O(n)
     * time (a similar algorithm is that of the array merge algorithm
     * in merge sort).

     * Base class for Angular Views, provides change detection functionality.
     * A change-detection tree collects all views that are to be checked for changes.
     * Use the methods to add and remove views from the tree, initiate change-detection,
     * and explicitly mark views as _dirty_, meaning that they have changed and need to be rerendered.
     *
     * \@usageNotes
     *
     * The following examples demonstrate how to modify default change-detection behavior
     * to perform explicit detection when needed.
     *
     * ### Use `markForCheck()` with `CheckOnce` strategy
     *
     * The following example sets the `OnPush` change-detection strategy for a component
     * (`CheckOnce`, rather than the default `CheckAlways`), then forces a second check
     * after an interval. See [live demo](http://plnkr.co/edit/GC512b?p=preview).
     *
     * <code-example path="core/ts/change_detect/change-detection.ts"
     * region="mark-for-check"></code-example>
     *
     * ### Detach change detector to limit how often check occurs
     *
     * The following example defines a component with a large list of read-only data
     * that is expected to change constantly, many times per second.
     * To improve performance, we want to check and update the list
     * less often than the changes actually occur. To do that, we detach
     * the component's change detector and perform an explicit local check every five seconds.
     *
     * <code-example path="core/ts/change_detect/change-detection.ts" region="detach"></code-example>
     *
     *
     * ### Reattaching a detached component
     *
     * The following example creates a component displaying live data.
     * The component detaches its change detector from the main change detector tree
     * when the `live` property is set to false, and reattaches it when the property
     * becomes true.

     * A ReflectiveDependency injection container used for instantiating objects and resolving
     * dependencies.
     *
     * An `Injector` is a replacement for a `new` operator, which can automatically resolve the
     * constructor dependencies.
     *
     * In typical use, application code asks for the dependencies in the constructor and they are
     * resolved by the `Injector`.
     *
     * \@usageNotes
     * ### Example
     *
     * The following example creates an `Injector` configured to create `Engine` and `Car`.
     *
     * ```typescript
     * \@Injectable()
     * class Engine {
     * }
     *
     * \@Injectable()
     * class Car {
     *   constructor(public engine:Engine) {}

     *
     * var injector = ReflectiveInjector.resolveAndCreate([Car, Engine]);
     * var car = injector.get(Car);
     * expect(car instanceof Car).toBe(true);
     * expect(car.engine instanceof Engine).toBe(true);
     * ```
     *
     * Notice, we don't use the `new` operator because we explicitly want to have the `Injector`
     * resolve all of the object's dependencies automatically.
     *
     * @deprecated from v5 - slow and brings in a lot of code, Use `Injector.create` instead.

    // called during a pre-order traversal of the view tree (that is calling the
    // parent hooks before the child hooks) these events are sent in using a
    // post-order traversal of the tree (children before parents). This changes the
    // meaning of initIndex in the view state. For ngOnInit, initIndex tracks the
    // expected nodeIndex which a ngOnInit should be called. When sending
    // ngAfterContentInit and ngAfterViewInit it is the expected count of
    // ngAfterContentInit or ngAfterViewInit methods that have been called. This
    // ensure that despite being called recursively or after picking up after an
    // exception, the ngAfterContentInit or ngAfterViewInit will be called on the
    // correct nodes. Consider for example, the following (where E is an element
    // and D is a directive)
    //  Tree:       pre-order index  post-order index
    //    E1        0                6
    //      E2      1                1
    //       D3     2                0
    //      E4      3                5
    //       E5     4                4
    //        E6    5                2
    //        E7    6                3
    // As can be seen, the post-order index has an unclear relationship to the
    // pre-order index (postOrderIndex === preOrderIndex - parentCount +
    // childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit
    // are stable (will be the same for the same view regardless of exceptions or
    // recursion) we just need to count them which will roughly correspond to the
    // post-order index (it skips elements and directives that do not have
    // lifecycle hooks).
    //
    // For example, if an exception is raised in the E6.onAfterViewInit() the
    // initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to
    // initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will
    // not have their ngAfterViewInit() called but, starting with E7, the rest of
    // the view will begin getting ngAfterViewInit() called until a check and
    // pass is complete.
    //
    // This algorthim also handles recursion. Consider if E4's ngAfterViewInit()
    // indirectly calls E1's ChangeDetectorRef.detectChanges(). The expected
    // initIndex is set to 6, the recusive checkAndUpdateView() starts walk again.
    // D3, E2, E6, E7, E5 and E4 are skipped, ngAfterViewInit() is called on E1.
    // When the recursion returns the initIndex will be 7 so E1 is skipped as it
    // has already been called in the recursively called checkAnUpdateView().

     * {\@a is-stable-examples}
     * ### isStable examples and caveats
     *
     * Note two important points about `isStable`, demonstrated in the examples below:
     * - the application will never be stable if you start any kind
     * of recurrent asynchronous task when the application starts
     * (for example for a polling process, started with a `setInterval`, a `setTimeout`
     * or using RxJS operators like `interval`);
     * - the `isStable` Observable runs outside of the Angular zone.
     *
     * Let's imagine that you start a recurrent task
     * (here incrementing a counter, using RxJS `interval`),
     * and at the same time subscribe to `isStable`.
     *
     * ```
     * constructor(appRef: ApplicationRef) {
     *   appRef.isStable.pipe(
     *      filter(stable => stable)
     *   ).subscribe(() => console.log('App is stable now');
     *   interval(1000).subscribe(counter => console.log(counter));
     * }
     * ```
     * In this example, `isStable` will never emit `true`,
     * and the trace "App is stable now" will never get logged.
     *
     * If you want to execute something when the app is stable,
     * you have to wait for the application to be stable
     * before starting your polling process.
     *
     * ```
     * constructor(appRef: ApplicationRef) {
     *   appRef.isStable.pipe(
     *     first(stable => stable),
     *     tap(stable => console.log('App is stable now')),
     *     switchMap(() => interval(1000))
     *   ).subscribe(counter => console.log(counter));
     * }
     * ```
     * In this example, the trace "App is stable now" will be logged
     * and then the counter starts incrementing every second.
     *
     * Note also that this Observable runs outside of the Angular zone,
     * which means that the code in the subscription
     * to this Observable will not trigger the change detection.
     *
     * Let's imagine that instead of logging the counter value,
     * you update a field of your component
     * and display it in its template.
     *
     * ```
     * constructor(appRef: ApplicationRef) {
     *   appRef.isStable.pipe(
     *     first(stable => stable),
     *     switchMap(() => interval(1000))
     *   ).subscribe(counter => this.value = counter);
     * }
     * ```
     * As the `isStable` Observable runs outside the zone,
     * the `value` field will be updated properly,
     * but the template will not be refreshed!
     *
     * You'll have to manually trigger the change detection to update the template.
     *
     * ```
     * constructor(appRef: ApplicationRef, cd: ChangeDetectorRef) {
     *   appRef.isStable.pipe(
     *     first(stable => stable),
     *     switchMap(() => interval(1000))
     *   ).subscribe(counter => {
     *     this.value = counter;
     *     cd.detectChanges();
     *   });
     * }
     * ```
     *
     * Or make the subscription callback run inside the zone.
     *
     * ```
     * constructor(appRef: ApplicationRef, zone: NgZone) {
     *   appRef.isStable.pipe(
     *     first(stable => stable),
     *     switchMap(() => interval(1000))
     *   ).subscribe(counter => zone.run(() => this.value = counter));
     * }
     * ```

       * When bootstrapping a new root component into an application, Angular mounts the

     * A regular expression that matches valid e-mail addresses.
     *
     * At a high level, this regexp matches e-mail addresses of the format `local-part\@tld`, where:
     * - `local-part` consists of one or more of the allowed characters (alphanumeric and some
     *   punctuation symbols).
     * - `local-part` cannot begin or end with a period (`.`).
     * - `local-part` cannot be longer than 64 characters.
     * - `tld` consists of one or more `labels` separated by periods (`.`). For example `localhost` or
     *   `foo.com`.
     * - A `label` consists of one or more of the allowed characters (alphanumeric, dashes (`-`) and
     *   periods (`.`)).
     * - A `label` cannot begin or end with a dash (`-`) or a period (`.`).
     * - A `label` cannot be longer than 63 characters.
     * - The whole address cannot be longer than 254 characters.
     *
     * ## Implementation background
     *
     * This regexp was ported over from AngularJS (see there for git history):
     * https://github.com/angular/angular.js/blob/c133ef836/src/ng/directive/input.js#L27
     * It is based on the
     * [WHATWG version](https://html.spec.whatwg.org/multipage/input.html#valid-e-mail-address) with
     * some enhancements to incorporate more RFC rules (such as rules related to domain names and the
     * lengths of different parts of the address). The main differences from the WHATWG version are:
     *   - Disallow `local-part` to begin or end with a period (`.`).
     *   - Disallow `local-part` length to exceed 64 characters.
     *   - Disallow total address length to exceed 254 characters.
     *
     * See [this commit](https://github.com/angular/angular.js/commit/f3f5cf72e) for more details.

     * `NgModel` directives.
     *
     * \@usageNotes
     *
     * ### Using select controls in a reactive form
     *
     * The following examples show how to use a select control in a reactive form.
     *
     * {\@example forms/ts/reactiveSelectControl/reactive_select_control_example.ts region='Component'}
     *
     * ### Using select controls in a template-driven form
     *
     * To use a select in a template-driven form, simply add an `ngModel` and a `name`
     * attribute to the main `<select>` tag.
     *
     * {\@example forms/ts/selectControl/select_control_example.ts region='Component'}
     *
     * ### Customizing option selection
     *
     * Angular uses object identity to select option. It's possible for the identities of items
     * to change while the data does not. This can happen, for example, if the items are produced
     * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the
     * second response will produce objects with different identities.
     *
     * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.
     * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.
     * If `compareWith` is given, Angular selects option by the return value of the function.
     *
     * ```ts
     * const selectedCountriesControl = new FormControl();
     * ```
     *
     * ```
     * <select [compareWith]="compareFn"  [formControl]="selectedCountriesControl">
     *     <option *ngFor="let country of countries" [ngValue]="country">
     *         {{country.name}}
     *     </option>
     * </select>
     *
     * compareFn(c1: Country, c2: Country): boolean {
     *     return c1 && c2 ? c1.id === c2.id : c1 === c2;
     * }
     * ```
     *
     * **Note:** We listen to the 'change' event because 'input' events aren't fired
     * for selects in Firefox and IE:
     * https://bugzilla.mozilla.org/show_bug.cgi?id=1024350
     * https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/4660045/

     *   </option>
     * </select>
     * ```

     *
     * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.

     *
     * ### Initializing Form Controls
     *
     * Instantiate a `FormControl`, with an initial value.
     *
     * ```ts
     * const control = new FormControl('some value');
     * console.log(control.value);     // 'some value'
     * ```
     *
     * The following example initializes the control with a form state object. The `value`
     * and `disabled` keys are required in this case.
     *
     * ```ts
     * const control = new FormControl({ value: 'n/a', disabled: true });
     * console.log(control.value);     // 'n/a'
     * console.log(control.status);    // 'DISABLED'
     * ```
     *
     * The following example initializes the control with a sync validator.
     *
     * ```ts
     * const control = new FormControl('', Validators.required);
     * console.log(control.value);      // ''
     * console.log(control.status);     // 'INVALID'
     * ```
     *
     * The following example initializes the control using an options object.
     *
     * ```ts
     * const control = new FormControl('', {
     *    validators: Validators.required,
     *    asyncValidators: myAsyncValidator
     * });
     * ```
     *
     * ### Configure the control to update on a blur event
     *
     * Set the `updateOn` option to `'blur'` to update on the blur `event`.
     *
     * ```ts
     * const control = new FormControl('', { updateOn: 'blur' });
     * ```
     *
     * ### Configure the control to update on a submit event
     *
     * Set the `updateOn` option to `'submit'` to update on a submit `event`.
     *
     * ```ts
     * const control = new FormControl('', { updateOn: 'submit' });
     * ```
     *
     * ### Reset the control back to an initial value
     *
     * You reset to a specific form state by passing through a standalone
     * value or a form state object that contains both a value and a disabled state
     * (these are the only two properties that cannot be calculated).
     *
     * ```ts
     * const control = new FormControl('Nancy');
     *
     * console.log(control.value); // 'Nancy'
     *
     * control.reset('Drew');
     *
     * console.log(control.value); // 'Drew'
     * ```
     *
     * ### Reset the control back to an initial value and disabled
     *
     * ```
     * const control = new FormControl('Nancy');
     *
     * console.log(control.value); // 'Nancy'
     * console.log(control.status); // 'VALID'
     *
     * control.reset({ value: 'Drew', disabled: true });
     *
     * console.log(control.value); // 'Drew'
     * console.log(control.status); // 'DISABLED'
     * ```

     * ### Create a form group with 2 controls

     * ### Create a form group with a group-level validator
     *
     * You include group-level validators as the second arg, or group-level async

     * that considers the value of more than one child control.

     * const form = new FormGroup({
     *   password: new FormControl('')
     *   passwordConfirm: new FormControl('')

     * ```
     *
     * ### Set the updateOn property for all controls in a form group
     *
     * The options object is used to set a default value for each child
     * control's `updateOn` property. If you set `updateOn` to `'blur'` at the
     * group level, all child controls default to 'blur', unless the child
     * has explicitly specified a different `updateOn` value.

     * A `FormArray` aggregates the values of each child `FormControl` into an array.
     * It calculates its status by reducing the status values of its children. For example, if one of
     * the controls in a `FormArray` is invalid, the entire array becomes invalid.

     * \@usageNotes

     * ### Create an array of form controls
     *
     * ```
     * const arr = new FormArray([
     *   new FormControl('Nancy', Validators.minLength(2)),
     *   new FormControl('Drew'),

     * ### Create a form array with array-level validators
     *
     * You include array-level validators and async validators. These come in handy
     * when you want to perform validation that considers the value of more than one child
     * control.
     *
     * The two types of validators are passed in separately as the second and third arg
     * respectively, or together as part of an options object.
     *
     * ```
     * const arr = new FormArray([
     *   new FormControl('Nancy'),
     *   new FormControl('Drew')
     * ], {validators: myValidator, asyncValidators: myAsyncValidator});
     * ```
     *
     * ### Set the updateOn property for all controls in a form array

     * \@description
     * Creates a top-level `FormGroup` instance and binds it to a form
     * to track aggregate form value and validation status.
     *
     * As soon as you import the `FormsModule`, this directive becomes active by default on
     * all `<form>` tags.  You don't need to add a special selector.
     *
     * You optionally export the directive into a local template variable using `ngForm` as the key
     * (ex: `#myForm="ngForm"`). This is optional, but useful.  Many properties from the underlying
     * `FormGroup` instance are duplicated on the directive itself, so a reference to it
     * gives you access to the aggregate value and validity status of the form, as well as
     * user interaction properties like `dirty` and `touched`.
     *
     * To register child controls with the form, use `NgModel` with a `name`
     * attribute. You may use `NgModelGroup` to create sub-groups within the form.
     *
     * If necessary, listen to the directive's `ngSubmit` event to be notified when the user has
     * triggered a form submission. The `ngSubmit` event emits the original form
     * submission event.
     *
     * In template driven forms, all `<form>` tags are automatically tagged as `NgForm`.
     * To import the `FormsModule` but skip its usage in some forms,
     * for example, to use native HTML5 validation, add the `ngNoForm` and the `<form>`
     * tags won't create an `NgForm` directive. In reactive forms, using `ngNoForm` is
     * unnecessary because the `<form>` tags are inert. In that case, you would
     * refrain from using the `formGroup` directive.
     *
     * \@usageNotes
     *
     * ### Migrating from deprecated ngForm selector
     *
     * Support for using `ngForm` element selector has been deprecated in Angular v6 and will be removed
     * in Angular v9.
     *
     * This has been deprecated to keep selectors consistent with other core Angular selectors,
     * as element selectors are typically written in kebab-case.
     *
     * Now deprecated:
     * ```html
     * <ngForm #myForm="ngForm">
     * ```
     *
     * After:
     * ```html
     * <ng-form #myForm="ngForm">
     * ```
     *
     * ### Listening for form submission
     *
     * The following example shows how to capture the form values from the "ngSubmit" event.
     *
     * {\@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
     *
     * ### Setting the update options
     *
     * The following example shows you how to change the "updateOn" option from its default using
     * ngFormOptions.
     *
     * ```html
     * <form [ngFormOptions]="{updateOn: 'blur'}">
     *    <input name="one" ngModel>  <!-- this ngModel will update on blur -->
     * </form>
     * ```

    /**
     * \@description
     * Creates a `FormControl` instance from a domain model and binds it
     * to a form control element.
     *
     * The `FormControl` instance tracks the value, user interaction, and
     * validation status of the control and keeps the view synced with the model. If used
     * within a parent form, the directive also registers itself with the form as a child
     * control.
     *
     * This directive is used by itself or as part of a larger form. Use the
     * `ngModel` selector to activate it.
     *
     * It accepts a domain model as an optional `Input`. If you have a one-way binding
     * to `ngModel` with `[]` syntax, changing the value of the domain model in the component
     * class sets the value in the view. If you have a two-way binding with `[()]` syntax
     * (also known as 'banana-box syntax'), the value in the UI always syncs back to
     * the domain model in your class.
     *
     * To inspect the properties of the associated `FormControl` (like validity state),
     * export the directive into a local template variable using `ngModel` as the key (ex: `#myVar="ngModel"`).
     * You then access the control using the directive's `control` property,
     * but most properties used (like `valid` and `dirty`) fall through to the control anyway for direct access.
     * See a full list of properties directly available in `AbstractControlDirective`.
     *
     * @see `RadioControlValueAccessor`
     * @see `SelectControlValueAccessor`
     *
     * \@usageNotes
     *
     * ### Using ngModel on a standalone control
     *
     * The following examples show a simple standalone control using `ngModel`:
     *
     * {\@example forms/ts/simpleNgModel/simple_ng_model_example.ts region='Component'}
     *
     * When using the `ngModel` within `<form>` tags, you'll also need to supply a `name` attribute
     * so that the control can be registered with the parent form under that name.
     *
     * In the context of a parent form, it's often unnecessary to include one-way or two-way binding,
     * as the parent form syncs the value for you. You access its properties by exporting it into a
     * local template variable using `ngForm` such as (`#f="ngForm"`). Use the variable where
     * needed on form submission.
     *
     * If you do need to populate initial values into your form, using a one-way binding for
     * `ngModel` tends to be sufficient as long as you use the exported form's value rather
     * than the domain model's value on submit.
     *
     * ### Using ngModel within a form
     *
     * The following example shows controls using `ngModel` within a form:
     *
     * {\@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
     *
     * ### Using a standalone ngModel within a group
     *
     * The following example shows you how to use a standalone ngModel control
     * within a form. This controls the display of the form, but doesn't contain form data.
     *
     * ```html
     * <form>
     *   <input name="login" ngModel placeholder="Login">
     *   <input type="checkbox" ngModel [ngModelOptions]="{standalone: true}"> Show more options?
     * </form>
     * <!-- form value: {login: ''} -->
     * ```
     *
     * ### Setting the ngModel name attribute through options
     *
     * The following example shows you an alternate way to set the name attribute. The name attribute is used
     * within a custom form component, and the name `\@Input` property serves a different purpose.
     *
     * ```html
     * <form>
     *   <my-person-control name="Nancy" ngModel [ngModelOptions]="{name: 'user'}">
     *   </my-person-control>
     * </form>

     * @see `AbstractControl`
     *
     * \@usageNotes
     *
     * ### Registering a single form control
     *
     * The following examples shows how to register a standalone control and set its value.
     *
     * {\@example forms/ts/simpleFormControl/simple_form_control_example.ts region='Component'}
     *
     * ### Use with ngModel
     *
     * Support for using the `ngModel` input property and `ngModelChange` event with reactive
     * form directives has been deprecated in Angular v6 and will be removed in Angular v7.
     *
     * Now deprecated:
     *
     * ```html
     * <input [formControl]="control" [(ngModel)]="value">
     * ```
     *
     * ```ts
     * this.value = 'some value';
     * ```
     *
     * This has been deprecated for a few reasons. First, developers have found this pattern
     * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's
     * an input/output property named `ngModel` on the reactive form directive that simply
     * approximates (some of) its behavior. Specifically, it allows getting/setting the value
     * and intercepting value events. However, some of `ngModel`'s other features - like
     * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,
     * which has understandably caused some confusion.
     *
     * In addition, this pattern mixes template-driven and reactive forms strategies, which
     * we generally don't recommend because it doesn't take advantage of the full benefits of
     * either strategy. Setting the value in the template violates the template-agnostic
     * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in
     * the class removes the convenience of defining forms in the template.
     *
     * To update your code before v7, you'll want to decide whether to stick with reactive form
     * directives (and get/set values using reactive forms patterns) or switch over to
     * template-driven directives.
     *
     * After (choice 1 - use reactive forms):
     *
     * ```html
     * <input [formControl]="control">
     * ```
     *
     * ```ts
     * this.control.setValue('some value');
     * ```
     *
     * After (choice 2 - use template-driven forms):
     *
     * ```html
     * <input [(ngModel)]="value">
     * ```
     *
     * ```ts
     * this.value = 'some value';
     * ```
     *
     * By default, when you use this pattern, you will see a deprecation warning once in dev
     * mode. You can choose to silence this warning by providing a config for
     * `ReactiveFormsModule` at import time:
     *
     * ```ts
     * imports: [
     *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});
     * ]
     * ```
     *
     * Alternatively, you can choose to surface a separate warning for each instance of this
     * pattern with a config value of `"always"`. This may help to track down where in the code
     * the pattern is being used as the code is being updated.
     *

     *
     * ### Register `FormControl` within a group
     *
     * The following example shows how to register multiple form controls within a form group
     * and set their value.
     *
     * {\@example forms/ts/simpleFormGroup/simple_form_group_example.ts region='Component'}
     *
     * To see `formControlName` examples with different form control types, see:
     *
     * * Radio buttons: `RadioControlValueAccessor`
     * * Selects: `SelectControlValueAccessor`
     *
     * ### Use with ngModel
     *
     * Support for using the `ngModel` input property and `ngModelChange` event with reactive
     * form directives has been deprecated in Angular v6 and will be removed in Angular v7.
     *
     * Now deprecated:
     *
     * ```html
     * <form [formGroup]="form">
     *   <input formControlName="first" [(ngModel)]="value">
     * </form>
     * ```
     *
     * ```ts
     * this.value = 'some value';
     * ```
     *
     * This has been deprecated for a few reasons. First, developers have found this pattern
     * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's
     * an input/output property named `ngModel` on the reactive form directive that simply
     * approximates (some of) its behavior. Specifically, it allows getting/setting the value
     * and intercepting value events. However, some of `ngModel`'s other features - like
     * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,
     * which has understandably caused some confusion.
     *
     * In addition, this pattern mixes template-driven and reactive forms strategies, which
     * we generally don't recommend because it doesn't take advantage of the full benefits of
     * either strategy. Setting the value in the template violates the template-agnostic
     * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in
     * the class removes the convenience of defining forms in the template.
     *
     * To update your code before v7, you'll want to decide whether to stick with reactive form
     * directives (and get/set values using reactive forms patterns) or switch over to
     * template-driven directives.
     *
     * After (choice 1 - use reactive forms):
     *
     * ```html
     * <form [formGroup]="form">
     *   <input formControlName="first">
     * </form>
     * ```
     *
     * ```ts
     * this.form.get('first').setValue('some value');
     * ```
     *
     * After (choice 2 - use template-driven forms):
     *
     * ```html
     * <input [(ngModel)]="value">
     * ```
     *
     * ```ts
     * this.value = 'some value';
     * ```
     *
     * By default, when you use this pattern, you will see a deprecation warning once in dev
     * mode. You can choose to silence this warning by providing a config for
     * `ReactiveFormsModule` at import time:
     *
     * ```ts
     * imports: [
     *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'})
     * ]
     * ```
     *
     * Alternatively, you can choose to surface a separate warning for each instance of this
     * pattern with a config value of `"always"`. This may help to track down where in the code
     * the pattern is being used as the code is being updated.

     * sanitized so that an attacker cannot inject e.g. a `javascript:` URL that would execute code on
     * the website.
     *
     * In specific situations, it might be necessary to disable sanitization, for example if the
     * application genuinely needs to produce a `javascript:` style link with a dynamic value in it.
     * Users can bypass security by constructing a value with one of the `bypassSecurityTrust...`
     * methods, and then binding to that value from the template.
     *
     * These situations should be very rare, and extraordinary care must be taken to avoid creating a
     * Cross Site Scripting (XSS) security bug!
     *
     * When using `bypassSecurityTrust...`, make sure to call the method as early as possible and as
     * close as possible to the source of the value, to make it easy to verify no security bug is
     * created by its use.
     *
     * It is not required (and not recommended) to bypass security if the value is safe, e.g. a URL that
     * does not start with a suspicious protocol, or an HTML snippet that does not contain dangerous
     * code. The sanitizer leaves safe values intact.
     *
     * \@security Calling any of the `bypassSecurityTrust...` APIs disables Angular's built-in
     * sanitization for the value passed in. Carefully check and audit all values and code paths going
     * into this call. Make sure any user data is appropriately escaped for this security context.
     * For more detail, see the [Security Guide](http://g.co/ng/security).

    /**
     * A configuration object that defines a single route.
     * A set of routes are collected in a `Routes` array to define a `Router` configuration.
     * The router attempts to match segments of a given URL against each route,
     * using the configuration options defined in this object.
     *
     * Supports static, parameterized, redirect, and wildcard routes, as well as
     * custom route data and resolve methods.
     *
     * For detailed usage information, see the [Routing Guide](guide/router).
     *
     * \@usageNotes
     *
     * ### Simple Configuration
     *
     * The following route specifies that when navigating to, for example,
     * `/team/11/user/bob`, the router creates the 'Team' component
     * with the 'User' child component in it.
     *
     * ```
     * [{
     *   path: 'team/:id',
     *  component: Team,
     *   children: [{
     *     path: 'user/:name',
     *     component: User
     *   }]
     * }]
     * ```
     *
     * ### Multiple Outlets
     *
     * The following route creates sibling components with multiple outlets.
     * When navigating to `/team/11(aux:chat/jim)`, the router creates the 'Team' component next to
     * the 'Chat' component. The 'Chat' component is placed into the 'aux' outlet.
     *
     * ```
     * [{
     *   path: 'team/:id',
     *   component: Team
     * }, {
     *   path: 'chat/:user',
     *   component: Chat
     *   outlet: 'aux'
     * }]
     * ```
     *
     * ### Wild Cards
     *
     * The following route uses wild-card notation to specify a component
     * that is always instantiated regardless of where you navigate to.
     *
     * ```
     * [{
     *   path: '**',
     *   component: WildcardComponent
     * }]
     * ```
     *
     * ### Redirects
     *
     * The following route uses the `redirectTo` property to ignore a segment of
     * a given URL when looking for a child path.
     *
     * When navigating to '/team/11/legacy/user/jim', the router changes the URL segment
     * '/team/11/legacy/user/jim' to '/team/11/user/jim', and then instantiates
     * the Team component with the User child component in it.
     *
     * ```
     * [{
     *   path: 'team/:id',
     *   component: Team,
     *   children: [{
     *     path: 'legacy/user/:name',
     *     redirectTo: 'user/:name'
     *   }, {
     *     path: 'user/:name',
     *     component: User
     *   }]
     * }]
     * ```
     *
     * The redirect path can be relative, as shown in this example, or absolute.
     * If we change the `redirectTo` value in the example to the absolute URL segment '/user/:name',
     * the result URL is also absolute, '/user/jim'.
     * ### Empty Path
     *
     * Empty-path route configurations can be used to instantiate components that do not 'consume'
     * any URL segments.
     *
     * In the following configuration, when navigating to
     * `/team/11`, the router instantiates the 'AllUsers' component.
     *
     * ```
     * [{
     *   path: 'team/:id',
     *   component: Team,
     *   children: [{
     *     path: '',
     *     component: AllUsers
     *   }, {
     *     path: 'user/:name',
     *     component: User
     *   }]
     * }]
     * ```
     *
     * Empty-path routes can have children. In the following example, when navigating
     * to `/team/11/user/jim`, the router instantiates the wrapper component with
     * the user component in it.
     *
     * Note that an empty path route inherits its parent's parameters and data.
     *
     * ```
     * [{
     *   path: 'team/:id',
     *   component: Team,
     *   children: [{
     *     path: '',
     *     component: WrapperCmp,
     *     children: [{
     *       path: 'user/:name',
     *       component: User
     *     }]
     *   }]
     * }]
     * ```
     *
     * ### Matching Strategy
     *
     * The default path-match strategy is 'prefix', which means that the router
     * checks URL elements from the left to see if the URL matches a specified path.
     * For example, '/team/11/user' matches 'team/:id'.
     *
     * ```
     * [{
     *   path: '',
     *   pathMatch: 'prefix', //default
     *   redirectTo: 'main'
     * }, {
     *   path: 'main',
     *   component: Main
     * }]
     * ```
     *
     * You can specify the path-match strategy 'full' to make sure that the path
     * covers the whole unconsumed URL. It is important to do this when redirecting
     * empty-path routes. Otherwise, because an empty path is a prefix of any URL,
     * the router would apply the redirect even when navigating to the redirect destination,
     * creating an endless loop.
     *
     * In the following example, supplying the 'full' `pathMatch` strategy ensures
     * that the router applies the redirect if and only if navigating to '/'.
     *
     * ```
     * [{
     *   path: '',
     *   pathMatch: 'full',
     *   redirectTo: 'main'
     * }, {
     *   path: 'main',
     *   component: Main
     * }]
     * ```
     *
     * ### Componentless Routes
     *
     * You can share parameters between sibling components.
     * For example, suppose that two sibling components should go next to each other,
     * and both of them require an ID parameter. You can accomplish this using a route
     * that does not specify a component at the top level.
     *
     * In the following example, 'MainChild' and 'AuxChild' are siblings.
     * When navigating to 'parent/10/(a//aux:b)', the route instantiates
     * the main child and aux child components next to each other.
     * For this to work, the application component must have the primary and aux outlets defined.
     *
     * ```
     * [{
     *    path: 'parent/:id',
     *    children: [
     *      { path: 'a', component: MainChild },
     *      { path: 'b', component: AuxChild, outlet: 'aux' }
     *    ]
     * }]
     * ```
     *
     * The router merges the parameters, data, and resolve of the componentless
     * parent into the parameters, data, and resolve of the children.
     *
     * This is especially useful when child components are defined
     * with an empty path string, as in the following example.
     * With this configuration, navigating to '/parent/10' creates
     * the main child and aux components.
     *
     * ```
     * [{
     *    path: 'parent/:id',
     *    children: [
     *      { path: '', component: MainChild },
     *      { path: '', component: AuxChild, outlet: 'aux' }
     *    ]
     * }]
     * ```
     *
     * ### Lazy Loading
     *
     * Lazy loading speeds up application load time by splitting the application
     * into multiple bundles and loading them on demand.
     * To use lazy loading, provide the `loadChildren` property  instead of the `children` property.
     *
     * Given the following example route, the router will lazy load
     * the associated module on demand using the browser native import system.
     *
     * ```
     * [{
     *   path: 'lazy',
     *   loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),
     * }];
     * ```

     *
     * Lets you link to specific routes in your app.
     *
     * Consider the following route configuration:
     * `[{ path: 'user/:name', component: UserCmp }]`.
     * When linking to this `user/:name` route, you use the `RouterLink` directive.
     *
     * If the link is static, you can use the directive as follows:
     * `<a routerLink="/user/bob">link to user component</a>`
     *
     * If you use dynamic values to generate the link, you can pass an array of path
     * segments, followed by the params for each segment.
     *
     * For instance `['/team', teamId, 'user', userName, {details: true}]`
     * means that we want to generate a link to `/team/11/user/bob;details=true`.
     *
     * Multiple static segments can be merged into one
     * (e.g., `['/team/11/user', userName, {details: true}]`).
     *
     * The first segment name can be prepended with `/`, `./`, or `../`:
     * * If the first segment begins with `/`, the router will look up the route from the root of the
     *   app.
     * * If the first segment begins with `./`, or doesn't begin with a slash, the router will
     *   instead look in the children of the current activated route.
     * * And if the first segment begins with `../`, the router will go up one level.
     *
     * You can set query params and fragment as follows:
     *
     * ```
     * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" fragment="education">
     *   link to user component
     * </a>
     * ```
     * RouterLink will use these to generate this link: `/user/bob#education?debug=true`.
     *
     * (Deprecated in v4.0.0 use `queryParamsHandling` instead) You can also tell the
     * directive to preserve the current query params and fragment:
     *
     * ```
     * <a [routerLink]="['/user/bob']" preserveQueryParams preserveFragment>
     *   link to user component
     * </a>
     * ```
     *
     * You can tell the directive how to handle queryParams. Available options are:
     *  - `'merge'`: merge the queryParams into the current queryParams
     *  - `'preserve'`: preserve the current queryParams
     *  - default/`''`: use the queryParams only
     *
     * Same options for {\@link NavigationExtras#queryParamsHandling
     * NavigationExtras#queryParamsHandling}.
     *
     * ```
     * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" queryParamsHandling="merge">
     *   link to user component
     * </a>
     * ```
     *
     * You can provide a `state` value to be persisted to the browser's History.state
     * property (See https://developer.mozilla.org/en-US/docs/Web/API/History#Properties). It's
     * used as follows:
     *
     * ```
     * <a [routerLink]="['/user/bob']" [state]="{tracingId: 123}">
     *   link to user component
     * </a>
     * ```
     *
     * And later the value can be read from the router through `router.getCurrentNavigation`.
     * For example, to capture the `tracingId` above during the `NavigationStart` event:
     *
     * ```
     * // Get NavigationStart events
     * router.events.pipe(filter(e => e instanceof NavigationStart)).subscribe(e => {
     *   const navigation = router.getCurrentNavigation();
     *   tracingService.trace({id: navigation.extras.state.tracingId});
     * });
     * ```
     *
     * The router link directive always treats the provided input as a delta to the current url.
     *
     * For instance, if the current url is `/user/(box//aux:team)`.
     *
     * Then the following link `<a [routerLink]="['/user/jim']">Jim</a>` will generate the link
     * `/user/(jim//aux:team)`.
     *
     * See {\@link Router#createUrlTree createUrlTree} for more information.

     * Lets you add a CSS class to an element when the link's route becomes active.
     *
     * This directive lets you add a CSS class to an element when the link's route
     * becomes active.
     *
     * Consider the following example:
     *
     * ```
     * <a routerLink="/user/bob" routerLinkActive="active-link">Bob</a>
     * ```
     *
     * When the url is either '/user' or '/user/bob', the active-link class will
     * be added to the `a` tag. If the url changes, the class will be removed.
     *
     * You can set more than one class, as follows:
     *
     * ```
     * <a routerLink="/user/bob" routerLinkActive="class1 class2">Bob</a>
     * <a routerLink="/user/bob" [routerLinkActive]="['class1', 'class2']">Bob</a>
     * ```
     *
     * You can configure RouterLinkActive by passing `exact: true`. This will add the classes
     * only when the url matches the link exactly.
     *
     * ```
     * <a routerLink="/user/bob" routerLinkActive="active-link" [routerLinkActiveOptions]="{exact:
     * true}">Bob</a>
     * ```
     *
     * You can assign the RouterLinkActive instance to a template variable and directly check
     * the `isActive` status.
     * ```
     * <a routerLink="/user/bob" routerLinkActive #rla="routerLinkActive">
     *   Bob {{ rla.isActive ? '(already open)' : ''}}
     * </a>
     * ```
     *
     * Finally, you can apply the RouterLinkActive directive to an ancestor of a RouterLink.
     *
     * ```
     * <div routerLinkActive="active-link" [routerLinkActiveOptions]="{exact: true}">
     *   <a routerLink="/user/jim">Jim</a>
     *   <a routerLink="/user/bob">Bob</a>
     * </div>
     * ```
     *
     * This will set the active-link class on the div tag if the url is either '/user/jim' or
     * '/user/bob'.

     *
     * That is why there are two ways to create the module: `RouterModule.forRoot` and

     *
     * * `forRoot` creates a module that contains all the directives, the given routes, and the router
     *   service itself.
     * * `forChild` creates a module that contains all the directives and the given routes, but does not
     *   include the router service.
     *
     * When registered at the root, the module should be used as follows
     *
     * ```
     * \@NgModule({

     * Adds router directives and providers.
     *
     * Managing state transitions is one of the hardest parts of building applications. This is
     * especially true on the web, where you also need to ensure that the state is reflected in the URL.
     * In addition, we often want to split applications into multiple bundles and load them on demand.
     * Doing this transparently is not trivial.
     *
     * The Angular router service solves these problems. Using the router, you can declaratively specify
     * application states, manage state transitions while taking care of the URL, and load bundles on
     * demand.
     *
     * @see [Routing and Navigation](guide/router.html) for an
