Annotation Type PreUpdate

@Target(value=METHOD)
@Retention(value=RUNTIME)
public @interface PreUpdate

Identifies the pre-update callback method which is invoked for an entity before the entity has been updated to the store. This method is run on the thread of the transaction flush or commit operation.

This annotation may be applied to an entity class method with the signature:
void <METHOD>()

or an entity listener class method with the signature:
void <METHOD>(Object).

The Object argument is the entity instance that the callback method is invoked. It may optionally be declared as the actual entity type. The callback method must not be static or final.

If this callback method throws an unchecked/runtime exception, then any transaction in which this callback is included will be rolled-back.
