Class EntityClassListener<T>

java.lang.Object

org.eclipse.persistence.descriptors.DescriptorEventAdapter

org.eclipse.persistence.internal.jpa.metadata.listeners.EntityListener<T>

org.eclipse.persistence.internal.jpa.metadata.listeners.EntityClassListener<T>

All Implemented Interfaces:

EventListener, DescriptorEventListener

public class EntityClassListener<T>
extends EntityListener<T>

A callback listener for those entities that define callback methods. Callback methods on an entity must be signatureless, hence, this class overrides behavior from EntityListener.

Since:

EclipseLink 1.0

Method Detail

addEventMethod

public void addEventMethod(String event,
                           Method method)

INTERNAL: For entity classes listener methods, they need to override listeners from mapped superclasses for the same method. So we need to override this method and make the override check instead of it throwing an exception for multiple lifecycle methods for the same event.

Overrides:

addEventMethod in class EntityListener<T>

getListenerClass

public Class getListenerClass()

INTERNAL:

Overrides:

getListenerClass in class EntityListener<T>

invokeMethod

protected void invokeMethod(String event,
                            DescriptorEvent descriptorEvent)

INTERNAL:

validateMethod

protected void validateMethod(Method method)

INTERNAL:

Overrides:

validateMethod in class EntityListener<T>
