Interface CallbackHandler

All Known Implementing Classes:
ExecutionContextImpl.NullCallbackHandler
public interface CallbackHandler
CallBack handlers receive notification of events on persistent objects. Handlers are responsible for invoking event listeners/callback methods on Callback or Listener implementations. When a validation handler is set, the prePersist, preStore and preDelete callbacks will be routed through to this validation handler.
