Class MetadataEntityClassListener

java.lang.Object

oracle.toplink.essentials.descriptors.DescriptorEventAdapter

oracle.toplink.essentials.internal.ejb.cmp3.metadata.listeners.MetadataEntityListener

oracle.toplink.essentials.internal.ejb.cmp3.metadata.listeners.MetadataEntityClassListener

All Implemented Interfaces:

java.util.EventListener, DescriptorEventListener

Direct Known Subclasses:

XMLEntityClassListener

public class MetadataEntityClassListener
extends MetadataEntityListener

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

Method Detail

addEventMethod

public void addEventMethod(java.lang.String event,
                           java.lang.reflect.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 MetadataEntityListener

getListenerClass

public java.lang.Class getListenerClass()

INTERNAL:

Overrides:

getListenerClass in class MetadataEntityListener

invokeMethod

protected void invokeMethod(java.lang.String event,
                            DescriptorEvent descriptorEvent)

INTERNAL:

Overrides:

invokeMethod in class MetadataEntityListener

isEntityClassListener

public boolean isEntityClassListener()

INTERNAL:

Overrides:

isEntityClassListener in class MetadataEntityListener

validateMethod

protected void validateMethod(java.lang.reflect.Method method)

INTERNAL:

Overrides:

validateMethod in class MetadataEntityListener
