 *
 * *Part of the [upgrade/static](api?query=upgrade%2Fstatic)
 * library for hybrid upgrade apps that support AOT compilation*
 *
 * This helper function returns a factory function to be used for registering
 * an AngularJS wrapper directive for "downgrading" an Angular component.
 *
 * @usageNotes
 * ### Examples
 *
 * Let's assume that you have an Angular component called `ng2Heroes` that needs
 * to be made available in AngularJS templates.
 *
 * {@example upgrade/static/ts/full/module.ts region="ng2-heroes"}
 *
 * We must create an AngularJS [directive](https://docs.angularjs.org/guide/directive)
 * that will make this Angular component available inside AngularJS templates.
 * The `downgradeComponent()` function returns a factory function that we
 * can use to define the AngularJS directive that wraps the "downgraded" component.
 *
 * {@example upgrade/static/ts/full/module.ts region="ng2-heroes-wrapper"}
 *
 * For more details and examples on downgrading Angular components to AngularJS components please
 * visit the [Upgrade guide](guide/upgrade#using-angular-components-from-angularjs-code).
 *
 * @param info contains information about the Component that is being downgraded:
 *
 * - `component: Type<any>`: The type of the Component that will be downgraded
 * - `downgradedModule?: string`: The name of the downgraded module (if any) that the component
 *   "belongs to", as returned by a call to `downgradeModule()`. It is the module, whose
 *   corresponding Angular module will be bootstrapped, when the component needs to be instantiated.
 *   <br />
 *   (This option is only necessary when using `downgradeModule()` to downgrade more than one
 *   Angular module.)
 * - `propagateDigest?: boolean`: Whether to perform {@link ChangeDetectorRef#detectChanges
 *   change detection} on the component on every
 *   [$digest](https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$digest). If set to `false`,
 *   change detection will still be performed when any of the component's inputs changes.
 *   (Default: true)
 *
 * @returns a factory function that can be used to register the component in an
 * AngularJS module.

                //   Note 2: It is possible that (while there are multiple downgraded modules) this

 *
 * This helper function returns a factory function that provides access to the Angular
 * service identified by the `token` parameter.
 *
 * @usageNotes
 * ### Examples
 *
 * First ensure that the service to be downgraded is provided in an `NgModule`
 * that will be part of the upgrade application. For example, let's assume we have
 * defined `HeroesService`
 *
 * {@example upgrade/static/ts/full/module.ts region="ng2-heroes-service"}
 *
 * and that we have included this in our upgrade app `NgModule`
 *
 * {@example upgrade/static/ts/full/module.ts region="ng2-module"}
 *
 * Now we can register the `downgradeInjectable` factory function for the service
 * on an AngularJS module.
 *
 * {@example upgrade/static/ts/full/module.ts region="downgrade-ng2-heroes-service"}
 *
 * Inside an AngularJS component's controller we can get hold of the
 * downgraded service via the name we gave when downgrading.
 *
 * {@example upgrade/static/ts/full/module.ts region="example-app"}
 *
 * <div class="alert is-important">
 *
 *   When using `downgradeModule()`, downgraded injectables will not be available until the Angular
 *   module that provides them is instantiated. In order to be safe, you need to ensure that the
 *   downgraded injectables are not used anywhere _outside_ the part of the app where it is
 *   guaranteed that their module has been instantiated.
 *
 *   For example, it is _OK_ to use a downgraded service in an upgraded component that is only used
 *   from a downgraded Angular component provided by the same Angular module as the injectable, but
 *   it is _not OK_ to use it in an AngularJS component that may be used independently of Angular or
 *   use it in a downgraded Angular component from a different module.
 *
 * </div>

/**
 * Use `UpgradeAdapter` to allow AngularJS and Angular to coexist in a single application.
 *
 * The `UpgradeAdapter` allows:
 * 1. creation of Angular component from AngularJS component directive
 *    (See [UpgradeAdapter#upgradeNg1Component()])
 * 2. creation of AngularJS directive from Angular component.
 *    (See [UpgradeAdapter#downgradeNg2Component()])
 * 3. Bootstrapping of a hybrid Angular application which contains both of the frameworks
 *    coexisting in a single application.
 *
 * @usageNotes
 * ### Mental Model
 *
 * When reasoning about how a hybrid application works it is useful to have a mental model which
 * describes what is happening and explains what is happening at the lowest level.
 *
 * 1. There are two independent frameworks running in a single application, each framework treats
 *    the other as a black box.
 * 2. Each DOM element on the page is owned exactly by one framework. Whichever framework
 *    instantiated the element is the owner. Each framework only updates/interacts with its own
 *    DOM elements and ignores others.
 * 3. AngularJS directives always execute inside AngularJS framework codebase regardless of
 *    where they are instantiated.
 * 4. Angular components always execute inside Angular framework codebase regardless of
 *    where they are instantiated.
 * 5. An AngularJS component can be upgraded to an Angular component. This creates an
 *    Angular directive, which bootstraps the AngularJS component directive in that location.
 * 6. An Angular component can be downgraded to an AngularJS component directive. This creates
 *    an AngularJS directive, which bootstraps the Angular component in that location.
 * 7. Whenever an adapter component is instantiated the host element is owned by the framework
 *    doing the instantiation. The other framework then instantiates and owns the view for that
 *    component. This implies that component bindings will always follow the semantics of the
 *    instantiation framework. The syntax is always that of Angular syntax.
 * 8. AngularJS is always bootstrapped first and owns the bottom most view.
 * 9. The new application is running in Angular zone, and therefore it no longer needs calls to
 *    `$apply()`.
 *
 * ### Example
 *
 * ```
 * const adapter = new UpgradeAdapter(forwardRef(() => MyNg2Module), myCompilerOptions);
 * const module = angular.module('myExample', []);
 * module.directive('ng2Comp', adapter.downgradeNg2Component(Ng2Component));
 *
 * module.directive('ng1Hello', function() {
 *   return {
 *      scope: { title: '=' },
 *      template: 'ng1[Hello {{title}}!](<span ng-transclude></span>)'
 *   };
 * });
 *
 *
 * @Component({
 *   selector: 'ng2-comp',
 *   inputs: ['name'],
 *   template: 'ng2[<ng1-hello [title]="name">transclude</ng1-hello>](<ng-content></ng-content>)',
 *   directives:
 * })
 * class Ng2Component {
 * }
 *
 * @NgModule({
 *   declarations: [Ng2Component, adapter.upgradeNg1Component('ng1Hello')],
 *   imports: [BrowserModule]
 * })
 * class MyNg2Module {}

 * document.body.innerHTML = '<ng2-comp name="World">project</ng2-comp>';

 * adapter.bootstrap(document.body, ['myExample']).ready(function() {
 *   expect(document.body.textContent).toEqual(
 *       "ng2[ng1[Hello World!](transclude)](project)");
 * });

 * [Ahead-of-Time compilation](guide/aot-compiler).

     *
     * 1. The component is instantiated by being listed in AngularJS template. This means that the

     *    Angular.

     *    syntax. This has to be done, this way because we must follow Angular components do not
     *    declare how the attributes should be interpreted.
     * 3. `ng-model` is controlled by AngularJS and communicates with the downgraded Angular component
     *    by way of the `ControlValueAccessor` interface from @angular/forms. Only components that
     *    implement this interface are eligible.
