Interface ObjectGridLifecycleListener

All Superinterfaces:

EventListener

public interface ObjectGridLifecycleListener
extends EventListener

Listener for ObjectGrid life cycle events.

An ObjectGridLifecycleListener implementation may also implement the ObjectGridPlugin interface in order to receive enhanced ObjectGrid plug-in lifecycle method calls. The plug-in is also required to correctly implement each of the bean methods related to introspection of its state (for example isInitialized(), isDestroyed(), etc).

Since:

7.1.1
