```
public interface NavigationStateManager
extends Serializable
```
An interface for handling interaction between Navigator and the browser location URI or other similar view identification and bookmarking system. The state is limited to a single string because in the usual cases it forms a part of a URI.
Different implementations can be created for hashbang URIs, HTML5 pushState, portlet URL navigation and other similar systems.
This interface is mostly for internal use by Navigator.
