Interface Callback

All Superinterfaces:

Serializable

All Known Implementing Classes:

AbstractCallback, EntityCallback, ListenerCallback

public interface Callback
extends Serializable

Represents a JPA event callback (the method).

Generally there are 2 flavors of this; either an annotated method on the entity itself or an annotated method on a separate "listener" class. This contract unifies both of these cases.
