Interface Summary

Interface	Description
ViewStateManager	The ViewStateManager is at the core of managing TopologyEventListeners, the 'view state' (changing vs changed) and sending out the appropriate and according TopologyEvents to the registered listeners - depending on the implementation it also supports the ClusterSyncService, which is invoked on handleNewView.

Class Summary

Class	Description
BaseTopologyView	Very simple abstract base class for the TopologyView which comes with the 'setNotCurrent()' method - that allows the ViewStateManager to mark a topologyView as no longer current - and the isCurrent() is handled accordingly.
DefaultClusterView	Default implementation of the ClusterView interface.
DefaultInstanceDescription	Base implementation for the InstanceDescription interface.
EventHelper	Contains static factory methods for creating TopologyEvents with BaseTopologyView as well as some TopologyEvent related helper methods
NonLocalInstanceDescription	InstanceDescription which represents an instance that is explicitly not local, ie isOwn==false.
