     * 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`.

     * Soy's EscapingConventions):
     * (1) Either an allowed protocol (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

     * It also disallows HTML entities in the first path part of a relative path,

    /**
     * Base class that 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 re-rendered.
     *
     * @see [Using change detection hooks](guide/lifecycle-hooks#using-change-detection-hooks)
     * @see [Defining custom change detection](guide/lifecycle-hooks#defining-custom-change-detection)
     *
     * @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.

     *
     * Logically `hostBindings` styling instructions are of lower priority than that of the template.
     * However, they execute after the template styling instructions. This means that they get inserted
     * in front of the template styling instructions.
     *
     * If we have a template styling instruction and a new `hostBindings` styling instruction is
     * executed it means that it may need to steal static fields from the template instruction. This
     * method allows us to update the first template instruction `TStylingKey` with a new value.
     *
     * Assume:
     * ```
     * <div my-dir style="color: red" [style.color]="tmplExp"></div>
     *
     * @Directive({
     *   host: {
     *     'style': 'width: 100px',
     *     '[style.color]': 'dirExp',
     *   }
     * })
     * class MyDir {}
     * ```
     *
     * when `[style.color]="tmplExp"` executes it creates this data structure.
     * ```
     *  ['', 'color', 'color', 'red', 'width', '100px'],
     * ```
     *
     * The reason for this is that the template instruction does not know if there are styling
     * instructions and must assume that there are none and must collect all of the static styling.
     * (both
     * `color' and 'width`)
     *
     * When `'[style.color]': 'dirExp',` executes we need to insert a new data into the linked list.
     * ```
     *  ['', 'color', 'width', '100px'],  // newly inserted
     *  ['', 'color', 'color', 'red', 'width', '100px'], // this is wrong
     * ```
     *
     * Notice that the template statics is now wrong as it incorrectly contains `width` so we need to
     * update it like so:
     * ```
     *  ['', 'color', 'width', '100px'],
     *  ['', 'color', 'color', 'red'],    // UPDATE
     * ```

    // 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().

     *
     * {@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));
     * }
     * ```
