Interface LeaseListener

All Known Implementing Classes:

LeasedListManager, LeaseListenerAdapter, LeastActiveSelector, ResourceCostSelector, RoundRobinSelector, ServiceResourceSelector

public interface LeaseListener

This interface defines the mechanism through which an entity receives notification that the ResourceLessor has determined that a lease has failed to renew itself and has been removed as a LeasedResource, or that an entity has cancelled it lease and has been removed as a LeasedResource. It is the responsibility of the entity to register with the ResourceLessor. The object that implements this interface should define the actions to take upon receipt of such notifications. Note that prior to sending the event, the ResourceLessor will remove the LeasedResource
