 * 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, `@angular/platform-browser` provides an
 * implementation specific to the browser environment, while `@angular/platform-server` provides
 * one suitable for use with server-side rendering.
 *
 * 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-agnostic.
