Callback (Hibernate Javadocs)

All Superinterfaces:

Serializable
```
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 presents a unified abstraction for both cases
