EntityListener (EclipseLink 2.6.3, "build v20160428-59c81c5" API Reference)

java.lang.Object
- org.eclipse.persistence.descriptors.DescriptorEventAdapter
- - org.eclipse.persistence.internal.jpa.metadata.listeners.EntityListener

All Implemented Interfaces:

java.util.EventListener, DescriptorEventListener

Direct Known Subclasses:

EntityClassListener
```
public class EntityListener
extends DescriptorEventAdapter
```
An EntityListener is placed on the owning entity's descriptor. Callback methods from an EntityListener require a signature on the method. Namely, they must have an Object parameter.

Since:

Eclipselink 1.0
