preClear(event) - JDO ClearLifecycleListener's method

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.

event - the clear event.
