 * implementation specific to the browser environment, while `@angular/platform-webworker` provides
 * one suitable for use with web workers.
 *
 * The `PlatformLocation` class is used directly by all implementations of {@link LocationStrategy}

 *
 * {@link LocationStrategy} in turn is used by the {@link Location} service which is used directly

 *
 * It's better to use {@link Router#navigate} service to trigger route changes. Use

 * `Location` is responsible for normalizing the URL against the application's base href.

 * @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`.

 *
 * The date-time pattern shows how to combine separate patterns for date (represented by {1})

 * What you want to pay attention to are:
 * - possibly removing a space for languages that don't use it, such as many East Asian languages
 * - possibly adding a comma, other punctuation, or a combining word
 *
 * For example:
 * - English uses `{1} 'at' {0}` or `{1}, {0}` (depending on date style), while Japanese uses
 *  `{1}{0}`.
 * - An English formatted date-time using the combining pattern `{1}, {0}` could be
 *  `Dec 10, 2010, 3:59:49 PM`. Notice the comma and space between the date portion and the time
 *  portion.
 *
 * There are four formats (`full`, `long`, `medium`, `short`); the determination of which to use
 * is normally based on the date style. For example, if the date has a full month and weekday
 * name, the full combining pattern will be used to combine that with a time. If the date has
 * numeric month, the short version of the combining pattern will be used to combine that with a
 * time. English uses `{1} 'at' {0}` for full and long styles, and `{1}, {0}` for medium and short

 *
 * Here are the special characters used in number patterns:
 *
 * | Symbol | Meaning |
 * |--------|---------|

 * | , | Replaced by the "grouping" (thousands) separator. |
 * | 0 | Replaced by a digit (or zero if there aren't enough digits). |
 * | # | Replaced by a digit (or nothing if there aren't enough). |
 * | ¤ | This will be replaced by a currency symbol, such as $ or USD. |
 * | % | This marks a percent format. The % symbol may change position, but must be retained. |
 * | E | This marks a scientific format. The E symbol may change position, but must be retained. |

 * Adds and removes CSS classes on an HTML element.
 *
 * The CSS classes are updated as follows, depending on the type of the expression evaluation:
 * - `string` - the CSS classes listed in the string (space delimited) are added,
 * - `Array` - the CSS classes declared as Array elements are added,
 * - `Object` - keys are CSS classes that get added when the expression given in the value
 *              evaluates to a truthy value, otherwise they are removed.

 * Instantiates a single {@link Component} type and inserts its Host View into current View.
 * `NgComponentOutlet` provides a declarative approach for dynamic component creation.
 *
 * `NgComponentOutlet` requires a component type, if a falsy value is set the view will clear and
 * any existing component will get destroyed.
 *
 * @usageNotes
 *
 * ### Fine tune control
 *
 * You can control the component creation process by using the following optional attributes:
 *
 * * `ngComponentOutletInjector`: Optional custom {@link Injector} that will be used as parent for
 * the Component. Defaults to the injector of the current view container.
 *
 * * `ngComponentOutletContent`: Optional list of projectable nodes to insert into the content
 * section of the component, if exists.
 *
 * * `ngComponentOutletNgModuleFactory`: Optional module factory to allow dynamically loading other
 * module, then load a component from that module.
 *
 * ### Syntax
 *
 * Simple
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
 * ```
 *
 * Customized injector/content
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   injector: injectorExpression;
 *                                   content: contentNodesExpression;">
 * </ng-container>
 * ```
 *
 * Customized ngModuleFactory
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   ngModuleFactory: moduleFactory;">
 * </ng-container>
 * ```
 *
 * ### A simple example
 *
 * {@example common/ngComponentOutlet/ts/module.ts region='SimpleExample'}
 *
 * A more complete example with additional options:
 *
 * {@example common/ngComponentOutlet/ts/module.ts region='CompleteExample'}

/**
 * The `NgForOf` directive instantiates a template once per item from an iterable. The context
 * for each instantiated template inherits from the outer context with the given loop variable
 * set to the current item from the iterable.
 *
 * @usageNotes
 *
 * ### Local Variables
 *
 * `NgForOf` provides several exported values that 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.
 *
 * ```
 * <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>
 * ```
 *
 * ### 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.
 * * Otherwise, the DOM element for that item will remain the same.
 *
 * 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 (such as `<input>` elements which accept user input) that are present. Inserted rows can
 * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
 * such as user input.
 *
 * It is possible for the identities of elements in the iterator to change while the data does not.
 * This can happen, for example, if the iterator 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, and Angular will tear down the entire DOM and rebuild it (as if all old
 * elements were deleted and all new elements inserted). This is an expensive operation and should
 * be avoided if possible.
 *
 * To customize the default tracking algorithm, `NgForOf` supports `trackBy` option.
 * `trackBy` takes a function which has two arguments: `index` and `item`.
 * If `trackBy` is given, Angular tracks changes by the return value of the function.
 *
 * ### Syntax
 *
 * - `<li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>`
 *
 * With `<ng-template>` element:
 *
 * ```
 * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
 *   <li>...</li>
 * </ng-template>
 * ```
 *
 * ### Example
 *
 * See a [live demo](http://plnkr.co/edit/KVuXxDp0qinGDyo307QW?p=preview) for a more detailed
 * example.

/**
 * Conditionally includes a template based on the value of an `expression`.
 *
 * `ngIf` evaluates the `expression` and then renders the `then` or `else` template in its place
 * when expression is truthy or falsy respectively. Typically the:
 *  - `then` template is the inline template of `ngIf` unless bound to a different value.
 *  - `else` template is blank unless it is bound.
 *
 *
 * @usageNotes
 *
 * ### Most common usage
 *
 * The most common usage of the `ngIf` directive is to conditionally show the inline template as
 * seen in this example:
 * {@example common/ngIf/ts/module.ts region='NgIfSimple'}
 *
 * ### Showing an alternative template using `else`
 *
 * If it is necessary to display a template when the `expression` is falsy use the `else` template
 * binding as shown. Note that the `else` binding points to a `<ng-template>` 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 non-inlined `then` template
 *
 * Usually the `then` template is the inlined template of the `ngIf`, but it can be changed using
 * a binding (just like `else`). Because `then` and `else` are bindings, the template references can
 * change at runtime as shown in this example.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
 *
 * ### Storing conditional result in a variable
 *
 * A common pattern is that we need to show a set of properties from the same object. If the
 * object is undefined, then we have to use the safe-traversal-operator `?.` to guard against
 * dereferencing a `null` value. This is especially the case when waiting on async data such as
 * when using the `async` pipe as shown in following example:
 *
 * ```
 * Hello {{ (userStream|async)?.last }}, {{ (userStream|async)?.first }}!
 * ```
 *
 * There are several inefficiencies in the above example:
 *  - We create multiple subscriptions on `userStream`. One for each `async` pipe, or two in the
 *    example above.
 *  - We cannot display an alternative screen while waiting for the data to arrive asynchronously.
 *  - We have to use the safe-traversal-operator `?.` to access properties, which is cumbersome.
 *  - We have to place the `async` pipe in parenthesis.
 *
 * A better way to do this is to use `ngIf` and store the result of the condition in a local
 * variable as shown in the the example below:
 *
 * {@example common/ngIf/ts/module.ts region='NgIfAs'}
 *
 * Notice that:
 *  - We use only one `async` pipe and hence only one subscription gets created.
 *  - `ngIf` stores the result of the `userStream|async` in the local variable `user`.
 *  - The local `user` can then be bound repeatedly in a more efficient way.
 *  - No need to use the safe-traversal-operator `?.` to access properties as `ngIf` will only
 *    display the data if `userStream` returns a value.
 *  - We can display an alternative template while waiting for the data.
 *
 * ### Syntax
 *
 * Simple form:
 * - `<div *ngIf="condition">...</div>`
 * - `<ng-template [ngIf]="condition"><div>...</div></ng-template>`
 *
 * Form with an else block:
 * ```
 * <div *ngIf="condition; else elseBlock">...</div>
 * <ng-template #elseBlock>...</ng-template>
 * ```
 *
 * Form with a `then` and `else` block:
 * ```
 * <div *ngIf="condition; then thenBlock else elseBlock"></div>
 * <ng-template #thenBlock>...</ng-template>
 * <ng-template #elseBlock>...</ng-template>
 * ```
 *
 * Form with storing the value locally:
 * ```
 * <div *ngIf="condition as value; else elseBlock">{{value}}</div>
 * <ng-template #elseBlock>...</ng-template>
 * ```

 * In javascript, only the components specified will be respected (not the ordering,
 * punctuations, ...) and details of the formatting will be dependent on the locale.
 *
 * Timezone of the formatted text will be the local system timezone of the end-user's machine.
 *
 * When the expression is a ISO string without time (e.g. 2016-09-19) the time zone offset is not
 * applied and the formatted text will have the same day, month and year of the expression.
 *
 * 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.

/**
 * @ngModule CommonModule
 * @description
 *
 * 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.
 *
 * @see `formatDate()`
 *
 *
 * @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.

 * Note that timezone correction is not applied to an ISO string that has no time component, such as "2016-09-19"
 *
 * ### 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:'mmss' }}        // 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();
 * }
 * ```

/*
  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     -/
 *    $5 = /pub/ietf/uri/    path
 *    $6 = <undefined>       query without ?
 *    $7 = Related           fragment without #
 * </pre>

/**
 * 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
 * parametrized 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`.
 *
 * @usageNotes
 * ### Basic Example
 *
 * ### Plain InjectionToken
 *
 * {@example core/di/ts/injector_spec.ts region='InjectionToken'}
 *
 * ### Tree-shakable InjectionToken

 * A pattern that recognizes a commonly useful subset of URLs that are safe.

 * This regular expression matches a subset of URLs that will not cause script
 * execution if used in URL context within a HTML document. Specifically, this
 * regular expression matches if (comment from here on and regex copied from
 * Soy's EscapingConventions):
 * (1) Either a protocol in a whitelist (http, https, mailto or ftp).
 * (2) or no protocol.  A protocol must be followed by a colon. The below
 *     allows that by allowing colons only after one of the characters [/?#].
 *     A colon after a hash (#) must be in the fragment.
 *     Otherwise, a colon after a (?) must be in a query.
 *     Otherwise, a colon after a single solidus (/) must be in a path.
 *     Otherwise, a colon after a double solidus (//) must be in the authority
 *     (before port).
 *
 * The pattern disallows &, used in HTML entity declarations before
 * one of the characters in [/?#]. This disallows HTML entities used in the
 * protocol name, which should never happen, e.g. "h&#116;tp" for "http".
 * It also disallows HTML entities in the first path part of a relative path,
 * e.g. "foo&lt;bar/baz".  Our existing escaping functions should not produce
 * that. More importantly, it disallows masking of a colon,
 * e.g. "javascript&#58;...".

/**
 * 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.

 * 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.

     * If we did not have this check then the insertion of `b` would:
     *   1) evict first `a`
     *   2) insert `b` at `0` index.
     *   3) leave `a` at index `1` as is. <-- this is wrong!
     *   3) reinsert `a` at index 2. <-- this is wrong!

     *   1) evict first `a`

     *   3) reinsert `a` at index 1.

     * The insertion of b will evict the first 'a'. If we don't reinsert it now it will be reinserted
     * at the end. Which will show up as the two 'a's switching position. This is incorrect, since a
     * better way to think of it is as insert of 'b' rather then switch 'a' with 'b' and then add 'a'

// This function calls the ngAfterContentCheck, ngAfterContentInit,
// ngAfterViewCheck, and ngAfterViewInit lifecycle hooks (depending on the node
// flags in lifecycle). Unlike ngDoCheck, ngOnChanges and ngOnInit, which are
// 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().

 * @description
 * The `ControlValueAccessor` for writing select control values and listening to select control
 * changes. The value accessor is used by the `FormControlDirective`, `FormControlName`, and
 * `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

/**
 * Tracks the value and validation status of an individual form control.
 *
 * This is one of the three fundamental building blocks of Angular forms, along with
 * `FormGroup` and `FormArray`. It extends the `AbstractControl` class that
 * implements most of the base functionality for accessing the value, validation status,
 * user interactions and events.
 *
 * @see `AbstractControl`
 * @see [Reactive Forms Guide](guide/reactive-forms)
 * @see [Usage Notes](#usage-notes)
 *
 * @usageNotes
 *
 * ### 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'

/**
 * Tracks the value and validity state of a group of `FormControl` instances.
 *
 * A `FormGroup` aggregates the values of each child `FormControl` into one object,
 * with each control name as the key.  It calculates its status by reducing the status values
 * of its children. For example, if one of the controls in a group is invalid, the entire
 * group becomes invalid.
 *
 * `FormGroup` is one of the three fundamental building blocks used to define forms in Angular,
 * along with `FormControl` and `FormArray`.
 *
 * When instantiating a `FormGroup`, pass in a collection of child controls as the first
 * argument. The key for each child registers the name for the control.
 *
 * @usageNotes
 *
 * ### Create a form group with 2 controls
 *
 * ```
 * const form = new FormGroup({
 *   first: new FormControl('Nancy', Validators.minLength(2)),
 *   last: new FormControl('Drew'),
 * });
 *
 * console.log(form.value);   // {first: 'Nancy', last; 'Drew'}
 * console.log(form.status);  // 'VALID'
 * ```
 *
 * ### Create a form group with a group-level validator
 *
 * You include group-level validators as the second arg, or group-level async
 * validators as the third arg. These come in handy when you want to perform validation
 * that considers the value of more than one child control.
 *
 * ```
 * const form = new FormGroup({
 *   password: new FormControl('', Validators.minLength(2)),
 *   passwordConfirm: new FormControl('', Validators.minLength(2)),
 * }, passwordMatchValidator);
 *
 *
 * function passwordMatchValidator(g: FormGroup) {
 *    return g.get('password').value === g.get('passwordConfirm').value
 *       ? null : {'mismatch': true};
 * }
 * ```
 *
 * Like `FormControl` instances, you choose to pass in
 * validators and async validators as part of an options object.
 *
 * ```
 * const form = new FormGroup({
 *   password: new FormControl('')
 *   passwordConfirm: new FormControl('')
 * }, { validators: passwordMatchValidator, asyncValidators: otherValidator });
 * ```
 *
 * ### 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.
 *
 * ```ts
 * const c = new FormGroup({
 *   one: new FormControl()
 * }, { updateOn: 'blur' });
 * ```

/**
 * Tracks the value and validity state of an array of `FormControl`,
 * `FormGroup` or `FormArray` instances.
 *
 * 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.
 *
 * `FormArray` is one of the three fundamental building blocks used to define forms in Angular,
 * along with `FormControl` and `FormGroup`.
 *
 * @usageNotes
 *
 * ### Create an array of form controls
 *
 * ```
 * const arr = new FormArray([
 *   new FormControl('Nancy', Validators.minLength(2)),
 *   new FormControl('Drew'),
 * ]);
 *
 * console.log(arr.value);   // ['Nancy', 'Drew']
 * console.log(arr.status);  // 'VALID'
 * ```
 *
 * ### 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
 *
 * 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
 * array level, all child controls default to 'blur', unless the child
 * has explicitly specified a different `updateOn` value.
 *
 * ```ts
 * const arr = new FormArray([
 *    new FormControl()
 * ], {updateOn: 'blur'});
 * ```
 *
 * ### Adding or removing controls from a form array
 *
 * To change the controls in the array, use the `push`, `insert`, or `removeAt` methods
 * in `FormArray` itself. These methods ensure the controls are properly tracked in the
 * form's hierarchy. Do not modify the array of `AbstractControl`s used to instantiate
 * the `FormArray` directly, as that result in strange and unexpected behavior such
 * as broken change detection.

 * @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 can 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
 * will give 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, you'll want to use `NgModel` with a
 * `name` attribute.  You can also use `NgModelGroup` if you'd like to create
 * sub-groups within the form.
 *
 * You can listen to the directive's `ngSubmit` event to be notified when the user has
 * triggered a form submission. The `ngSubmit` event will be emitted with the original form
 * submission event.
 *
 * In template driven forms, all `<form>` tags are automatically tagged as `NgForm`.
 * If you want to import the `FormsModule` but skip its usage in some forms,
 * for example, to use native HTML5 validation, you can add `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.
 *
 * 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">
 * ```

 * Creates a `FormControl` instance from a domain model and binds it
 * to a form control element.
 *
 * The `FormControl` instance will track the value, user interaction, and
 * validation status of the control and keep the view synced with the model. If used
 * within a parent form, the directive will also register itself with the form as a child
 * control.
 *
 * This directive can be used by itself or as part of a larger form. All you need is 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 will set 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 will always be synced back to
 * the domain model in your class as well.
 *
 * If you wish to inspect the properties of the associated `FormControl` (like
 * validity state), you can also export the directive into a local template variable using
 * `ngModel` as the key (ex: `#myVar="ngModel"`). You can then access the control using the
 * directive's `control` property, but most properties you'll need (like `valid` and `dirty`)
 * will fall through to the control anyway, so you can access them directly. You can see a
 * full list of properties directly available in `AbstractControlDirective`.
 *
 * The following is an example of 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.
 *
 * It's worth noting that in the context of a parent form, you often can skip one-way or
 * two-way binding because the parent form will sync the value for you. You can access
 * its properties by exporting it into a local template variable using `ngForm` (ex:
 * `#f="ngForm"`). Then you can pass it where it needs to go on submit.
 *
 * 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.
 *
 * Take a look at an example of using `ngModel` within a form:
 *
 * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
 *

/**
 * @description
 * * Syncs a standalone `FormControl` instance to a form control element.
 *
 * @see [Reactive Forms Guide](guide/reactive-forms)
 * @see `FormControl`
 * @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.
 *

 * @description
 * Syncs a `FormControl` in an existing `FormGroup` to a form control
 * element by name.
 *
 * @see [Reactive Forms Guide](guide/reactive-forms)
 * @see `FormControl`
 * @see `AbstractControl`
 *
 * @usageNotes
 *
 * ### 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.

/**
 * DomSanitizer helps preventing Cross Site Scripting Security bugs (XSS) by sanitizing
 * values to be safe to use in the different DOM contexts.
 *
 * For example, when binding a URL in an `<a [href]="someValue">` hyperlink, `someValue` will be
 * 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.

 * 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 to 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>
 * ```
 *
 * 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.

 * @description
 *
 * 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'.

/**
 * @usageNotes
 *
 * RouterModule can be imported multiple times: once per lazily-loaded bundle.
 * Since the router deals with a global shared resource--location, we cannot have
 * more than one router service active.
 *
 * That is why there are two ways to create the module: `RouterModule.forRoot` and
 * `RouterModule.forChild`.
 *
 * * `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({
 *   imports: [RouterModule.forRoot(ROUTES)]
 * })
 * class MyNgModule {}
 * ```
 *
 * For submodules and lazy loaded submodules the module should be used as follows:
 *
 * ```
 * @NgModule({
 *   imports: [RouterModule.forChild(ROUTES)]
 * })
 * class MyNgModule {}
 * ```
 *
 * @description
 *
 * 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 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.
 *
 * [Read this developer guide](https://angular.io/docs/ts/latest/guide/router.html) to get an
 * overview of how the router should be used.

//  This file creates a global JSONBigNumber object containing two methods: stringify
//  and parse.

//      JSONBigNumber.stringify(value, replacer, space)
//          value       any JavaScript value, usually an object or array.
//          replacer    an optional parameter that determines how object
//                      values are stringified for objects. It can be a
//                      function or an array of strings.
//          space       an optional parameter that specifies the indentation
//                      of nested structures. If it is omitted, the text will
//                      be packed without extra whitespace. If it is a number,
//                      it will specify the number of spaces to indent at each
//                      level. If it is a string (such as "\t" or "&nbsp;"),
//                      it contains the characters used to indent at each level.
//          This method produces a JSON text from a JavaScript value.
//          When an object value is found, if the object contains a toJSON
//          method, its toJSON method will be called and the result will be
//          stringified. A toJSON method does not serialize: it returns the
//          value represented by the name/value pair that should be serialized,
//          or undefined if nothing should be serialized. The toJSON method
//          will be passed the key associated with the value, and this will be
//          bound to the value.

//          For example, this would serialize Dates as ISO strings.

//              Date.prototype.toJSON = function (key) {
//                  function f(n) {
//                      // Format integers to have at least two digits.
//                      return (n < 10)
//                          ? "0" + n
//                          : n;
//                  }
//                  return this.getUTCFullYear()   + "-" +
//                       f(this.getUTCMonth() + 1) + "-" +
//                       f(this.getUTCDate())      + "T" +
//                       f(this.getUTCHours())     + ":" +
//                       f(this.getUTCMinutes())   + ":" +
//                       f(this.getUTCSeconds())   + "Z";
//              };

//          You can provide an optional replacer method. It will be passed the
//          key and value of each member, with this bound to the containing
//          object. The value that is returned from your method will be
//          serialized. If your method returns undefined, then the member will
//          be excluded from the serialization.

//          If the replacer parameter is an array of strings, then it will be
//          used to select the members to be serialized. It filters the results
//          such that only members with keys listed in the replacer array are
//          stringified.

//          Values that do not have JSON representations, such as undefined or
//          functions, will not be serialized. Such values in objects will be
//          dropped; in arrays they will be replaced with null. You can use
//          a replacer function to replace those with JSON values.

//          JSONBigNumber.stringify(undefined) returns undefined.

//          The optional space parameter produces a stringification of the
//          value that is filled with line breaks and indentation to make it
//          easier to read.

//          If the space parameter is a non-empty string, then that string will
//          be used for indentation. If the space parameter is a number, then
//          the indentation will be that many spaces.

//          Example:

//          text = JSONBigNumber.stringify(["e", {pluribus: "unum"}]);
//          // text is '["e",{"pluribus":"unum"}]'

//          text = JSONBigNumber.stringify(["e", {pluribus: "unum"}], null, "\t");
//          // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'

//          text = JSONBigNumber.stringify([new Date()], function (key, value) {
//              return this[key] instanceof Date
//                  ? "Date(" + this[key] + ")"
//                  : value;
//          });
//          // text is '["Date(---current time---)"]'

//      JSONBigNumber.parse(text, reviver)
//          This method parses a JSON text to produce an object or array.
//          It can throw a SyntaxError exception.

//          The optional reviver parameter is a function that can filter and
//          transform the results. It receives each of the keys and values,
//          and its return value is used instead of the original value.
//          If it returns what it received, then the structure is not modified.
//          If it returns undefined then the member is deleted.

//          Example:

//          // Parse the text. Values that look like ISO date strings will
//          // be converted to Date objects.

//          myData = JSONBigNumber.parse(text, function (key, value) {
//              var a;
//              if (typeof value === "string") {
//                  a =
//   /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
//                  if (a) {
//                      return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
//                          +a[5], +a[6]));
//                  }
//              }
//              return value;
//          });

//          myData = JSONBigNumber.parse('["Date(09/09/2001)"]', function (key, value) {
//              var d;
//              if (typeof value === "string" &&
//                      value.slice(0, 5) === "Date(" &&
