- com.vaadin.navigator.Navigator.UriFragmentManager

All Implemented Interfaces:

NavigationStateManager, Page.UriFragmentChangedListener, Serializable

Enclosing class:

Navigator
```
public static class Navigator.UriFragmentManager
extends Object
implements NavigationStateManager, Page.UriFragmentChangedListener
```
A NavigationStateManager using hashbang fragments in the Page location URI to track views and enable listening to view changes.
A hashbang URI is one where the optional fragment or "hash" part - the part following a # sign - is used to encode navigation state in a web application. The advantage of this is that the fragment can be dynamically manipulated by javascript without causing page reloads.
This class is mostly for internal use by Navigator, and is only public and static to enable testing.
