/**
|
|
* This class should not be used directly by an application developer. Instead, use
|
|
* {@link Location}.
|
|
*
|
|
* `PlatformLocation` encapsulates all calls to DOM apis, which allows the Router to be platform
|
|
* agnostic.
|
|
* This means that we can have different implementation of `PlatformLocation` for the different
|
|
* platforms
|
|
* that angular supports. For example, the default `PlatformLocation` is {@link
|
|
* BrowserPlatformLocation},
|
|
* however when you run your app in a WebWorker you use {@link WebWorkerPlatformLocation}.
|
|
*
|
|
* The `PlatformLocation` class is used directly by all implementations of {@link LocationStrategy}
|
|
* when
|
|
* they need to interact with the DOM apis like pushState, popState, etc...
|
|
*
|
|
* {@link LocationStrategy} in turn is used by the {@link Location} service which is used directly
|
|
* by
|
|
* the {@link Router} in order to navigate between routes. Since all interactions between {@link
|
|
* Router} /
|
|
* {@link Location} / {@link LocationStrategy} and DOM apis flow through the `PlatformLocation`
|
|
* class
|
|
* they are all platform independent.
