* A helper function that allows an Angular component to be used from AngularJS.
*
* *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.

* A helper function to allow an Angular service to be accessible from AngularJS.
*
* *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 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>
*
* @param token an `InjectionToken` that identifies a service provided from Angular.
* @param downgradedModule the name of the downgraded module (if any) that the injectable
* "belongs to", as returned by a call to `downgradeModule()`. It is the module, whose injector will
* be used for instantiating the injectable.<br />
* (This option is only necessary when using `downgradeModule()` to downgrade more than one Angular
* module.)
*
* @returns a [factory function](https://docs.angularjs.org/guide/di) that can be
* used to register the service on an AngularJS module.

/**
* @description
*
* A helper function for creating an AngularJS module that can bootstrap an Angular module
* "on-demand" (possibly lazily) when a {@link downgradeComponent downgraded component} needs to be
* instantiated.
*
* *Part of the [upgrade/static](api?query=upgrade/static) library for hybrid upgrade apps that
* support AOT compilation.*
*
* It allows loading/bootstrapping the Angular part of a hybrid application lazily and not having to
* pay the cost up-front. For example, you can have an AngularJS application that uses Angular for
* specific routes and only instantiate the Angular modules if/when the user visits one of these
* routes.
*
* The Angular module will be bootstrapped once (when requested for the first time) and the same
* reference will be used from that point onwards.
*
* `downgradeModule()` requires either an `NgModuleFactory` or a function:
* - `NgModuleFactory`: If you pass an `NgModuleFactory`, it will be used to instantiate a module
* using `platformBrowser`'s {@link PlatformRef#bootstrapModuleFactory bootstrapModuleFactory()}.
* - `Function`: If you pass a function, it is expected to return a promise resolving to an
* `NgModuleRef`. The function is called with an array of extra {@link StaticProvider Providers}
* that are expected to be available from the returned `NgModuleRef`'s `Injector`.
*
* `downgradeModule()` returns the name of the created AngularJS wrapper module. You can use it to
* declare a dependency in your main AngularJS module.
*
* {@example upgrade/static/ts/lite/module.ts region="basic-how-to"}
*
* For more details on how to use `downgradeModule()` see
* [Upgrading for Performance](guide/upgrade-performance).
*
* @usageNotes
*
* Apart from `UpgradeModule`, you can use the rest of the `upgrade/static` helpers as usual to
* build a hybrid application. Note that the Angular pieces (e.g. downgraded services) will not be
* available until the downgraded module has been bootstrapped, i.e. by instantiating a downgraded
* component.
*
* <div class="alert is-important">
*
* You cannot use `downgradeModule()` and `UpgradeModule` in the same hybrid application.<br />
* Use one or the other.
*
* </div>
*
* ### Differences with `UpgradeModule`
*
* Besides their different API, there are two important internal differences between
* `downgradeModule()` and `UpgradeModule` that affect the behavior of hybrid applications:
*
* 1. Unlike `UpgradeModule`, `downgradeModule()` does not bootstrap the main AngularJS module
* inside the {@link NgZone Angular zone}.
* 2. Unlike `UpgradeModule`, `downgradeModule()` does not automatically run a
* [$digest()](https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$digest) when changes are
* detected in the Angular part of the application.
*
* What this means is that applications using `UpgradeModule` will run change detection more
* frequently in order to ensure that both frameworks are properly notified about possible changes.
* This will inevitably result in more change detection runs than necessary.
*
* `downgradeModule()`, on the other side, does not try to tie the two change detection systems as
* tightly, restricting the explicit change detection runs only to cases where it knows it is
* necessary (e.g. when the inputs of a downgraded component change). This improves performance,
* especially in change-detection-heavy applications, but leaves it up to the developer to manually
* notify each framework as needed.
*
* For a more detailed discussion of the differences and their implications, see
* [Upgrading for Performance](guide/upgrade-performance).
*
* <div class="alert is-helpful">
*
* You can manually trigger a change detection run in AngularJS using
* [scope.$apply(...)](https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$apply) or
* [$rootScope.$digest()](https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$digest).
*
* You can manually trigger a change detection run in Angular using {@link NgZone#run
* ngZone.run(...)}.
*
* </div>
*
* ### Downgrading multiple modules
*
* It is possible to downgrade multiple modules and include them in an AngularJS application. In
* that case, each downgraded module will be bootstrapped when an associated downgraded component or
* injectable needs to be instantiated.
*
* Things to keep in mind, when downgrading multiple modules:
*
* - Each downgraded component/injectable needs to be explicitly associated with a downgraded
* module. See `downgradeComponent()` and `downgradeInjectable()` for more details.
*
* - If you want some injectables to be shared among all downgraded modules, you can provide them as
* `StaticProvider`s, when creating the `PlatformRef` (e.g. via `platformBrowser` or
* `platformBrowserDynamic`).
*
* - When using {@link PlatformRef#bootstrapmodule `bootstrapModule()`} or
* {@link PlatformRef#bootstrapmodulefactory `bootstrapModuleFactory()`} to bootstrap the
* downgraded modules, each one is considered a "root" module. As a consequence, a new instance
* will be created for every injectable provided in `"root"` (via
* {@link Injectable#providedIn `providedIn`}).
* If this is not your intention, you can have a shared module (that will act as act as the "root"
* module) and create all downgraded modules using that module's injector:
*
* {@example upgrade/static/ts/lite-multi-shared/module.ts region="shared-root-module"}
*

*

* available inside Angular templates.
*
* {@example upgrade/static/ts/full/module.ts region="ng1-hero-wrapper"}
*
* In this example you can see that we must derive from the `UpgradeComponent`
* base class but also provide an {@link Directive `@Directive`} decorator. This is
* because the AOT compiler requires that this information is statically available at
* compile time.
*
* Note that we must do the following:
* * specify the directive's selector (`ng1-hero`)
* * specify all inputs and outputs that the AngularJS component expects
* * derive from `UpgradeComponent`
* * call the base class from the constructor, passing
* * the AngularJS name of the component (`ng1Hero`)

*
* *Part of the [upgrade/static](api?query=upgrade/static)
* library for hybrid upgrade apps that support AOT compilation*
*
* The `upgrade/static` package contains helpers that allow AngularJS and Angular components
* to be used together inside a hybrid upgrade application, which supports AOT compilation.
*
* Specifically, the classes and functions in the `upgrade/static` module allow the following:
*
* 1. Creation of an Angular directive that wraps and exposes an AngularJS component so
* that it can be used in an Angular template. See `UpgradeComponent`.
* 2. Creation of an AngularJS directive that wraps and exposes an Angular component so
* that it can be used in an AngularJS template. See `downgradeComponent`.
* 3. Creation of an Angular root injector provider that wraps and exposes an AngularJS
* service so that it can be injected into an Angular context. See
* {@link UpgradeModule#upgrading-an-angular-1-service Upgrading an AngularJS service} below.
* 4. Creation of an AngularJS service that wraps and exposes an Angular injectable
* so that it can be injected into an AngularJS context. See `downgradeInjectable`.
* 3. Bootstrapping of a hybrid Angular application which contains both of the frameworks
* coexisting in a single application.
*
* @usageNotes
*
* ```ts
* import {UpgradeModule} from '@angular/upgrade/static';
* ```
*
* See also the {@link UpgradeModule#examples examples} below.
*
* ### 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 the AngularJS framework codebase regardless of
* where they are instantiated.
* 4. Angular components always execute inside the Angular framework codebase regardless of
* where they are instantiated.
* 5. An AngularJS component can be "upgraded"" to an Angular component. This is achieved by
* defining an Angular directive, which bootstraps the AngularJS component at its location
* in the DOM. See `UpgradeComponent`.
* 6. An Angular component can be "downgraded" to an AngularJS component. This is achieved by
* defining an AngularJS directive, which bootstraps the Angular component at its location
* in the DOM. See `downgradeComponent`.
* 7. Whenever an "upgraded"/"downgraded" 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.
* 1. This implies that the component bindings will always follow the semantics of the
* instantiation framework.
* 2. The DOM attributes are parsed by the framework that owns the current template. So
* attributes in AngularJS templates must use kebab-case, while AngularJS templates must use
* camelCase.
* 3. However the template binding syntax will always use the Angular style, e.g. square
* brackets (`[...]`) for property binding.
* 8. Angular is bootstrapped first; AngularJS is bootstrapped second. AngularJS always owns the
* root component of the application.
* 9. The new application is running in an Angular zone, and therefore it no longer needs calls to
* `$apply()`.
*
* ### The `UpgradeModule` class
*
* This class is an `NgModule`, which you import to provide AngularJS core services,
* and has an instance method used to bootstrap the hybrid upgrade application.
*
* * Core AngularJS services
* Importing this `NgModule` will add providers for the core
* [AngularJS services](https://docs.angularjs.org/api/ng/service) to the root injector.
*
* * Bootstrap
* The runtime instance of this class contains a {@link UpgradeModule#bootstrap `bootstrap()`}
* method, which you use to bootstrap the top level AngularJS module onto an element in the
* DOM for the hybrid upgrade app.
*
* It also contains properties to access the {@link UpgradeModule#injector root injector}, the
* bootstrap `NgZone` and the
* [AngularJS $injector](https://docs.angularjs.org/api/auto/service/$injector).
*
* ### Examples
*
* Import the `UpgradeModule` into your top level {@link NgModule Angular `NgModule`}.
*
* {@example upgrade/static/ts/full/module.ts region='ng2-module'}
*
* Then inject `UpgradeModule` into your Angular `NgModule` and use it to bootstrap the top level
* [AngularJS module](https://docs.angularjs.org/api/ng/type/angular.Module) in the
* `ngDoBootstrap()` method.
*
* {@example upgrade/static/ts/full/module.ts region='bootstrap-ng1'}
*
* Finally, kick off the whole process, by bootstraping your top level Angular `NgModule`.
*
* {@example upgrade/static/ts/full/module.ts region='bootstrap-ng2'}
*
* {@a upgrading-an-angular-1-service}
* ### Upgrading an AngularJS service
*
* There is no specific API for upgrading an AngularJS service. Instead you should just follow the
* following recipe:
*
* Let's say you have an AngularJS service:
*
* {@example upgrade/static/ts/full/module.ts region="ng1-text-formatter-service"}
*
* Then you should define an Angular provider to be included in your `NgModule` `providers`
* property.
*
* {@example upgrade/static/ts/full/module.ts region="upgrade-ng1-service"}
*
* Then you can use the "upgraded" AngularJS service by injecting it into an Angular component
* or service.
*
* {@example upgrade/static/ts/full/module.ts region="use-ng1-upgraded-service"}
