Class HistoryImplPushState

java.lang.Object

io.crysknife.ui.navigation.client.local.pushstate.HistoryImplPushState

All Implemented Interfaces:

org.gwtproject.event.logical.shared.HasValueChangeHandlers<String>, org.gwtproject.event.shared.HasHandlers

public class HistoryImplPushState
extends Object
implements org.gwtproject.event.logical.shared.HasValueChangeHandlers<String>

Enhances GWT's History implementation to add HTML5 pushState support.

This class no longer inherits from HistoryImpl to allow for compatibility with both GWT 2.6 and GWT 2.7+. HistoryImpl was moved in GWT 2.7 and is no longer accessible. The previously inherited methods are now part of this class.

The complete path is treated as history token.

The leading '/' is hidden from GWTs History API, so that the path '/' is returned as an empty history token ('').
