Interface ClearLifecycleListener

Superinterfaces:
InstanceLifecycleListener
This interface is implemented by listeners to be notified of clear events.
Since:
JDO 2.0
This method is called after the ClearCallback.jdoPreClear method is invoked on the instance and the fields have been cleared by the JDO implementation.
This method is called after the ClearCallback.jdoPreClear method is invoked on the instance and the fields have been cleared by the JDO implementation.
Parameters:
event - the clear event.
Since:
JDO 2.0
This method is called before the implementation calls the instance method ClearCallback.jdoPreClear and before it clears the values in the instance to their Java default values.
This method is called before the implementation calls the instance method ClearCallback.jdoPreClear and before it clears the values in the instance to their Java default values. This happens during an application call to evict, and in afterCompletion for commit with RetainValues false and rollback with RestoreValues false.

The method is called during any state transition to hollow. Non-persistent, non-transactional fields should be cleared in this method. Associations between this instance and others in the runtime environment should be cleared.

This method is not modified by the enhancer, so access to fields is not mediated.

Parameters:
event - the clear event.
Since:
JDO 2.0
