All Implemented Interfaces:

IListener

public class LeaseListener
extends java.lang.Object
implements IListener

The lease listener is a helper class that can be used as a default listener at the lease registry if the detection of an expired lease should only be performed at certain times. Incoming state changes are signalled via notification to the listener itself, thus users can wait on the listener, if desired.
