Interface ObjectExpirationListener

All Superinterfaces:

java.util.EventListener

public interface ObjectExpirationListener
extends java.util.EventListener

The interface clients use to receive callback notifications when an object is removed from StateServer.

Clients may register an instance of this interface with DataAccessor.addListener(ObjectExpirationListener). The listener will be called when any objects created in an application namespace registered for event notification callbacks via StateServerKey.appNameToId(String, boolean) expire.

Typically, there are multiple StateServer client instances on multiple machines in, say, a web farm. In that case, multiple client instances may be registered for object expiration callbacks. StateServer will choose one of those client instances to deliver any particular event notification to - it will not broadcast the event notification to all registered clients.
