javax.jdo.listener.InstanceLifecycleEvent
This is the event class used in life cycle event notifications.(Class of JDO)
preClear(event)
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.(Method of javax.jdo.listener.ClearLifecycleListener)
preStore(event)
Invoked whenever a persistent instance is stored, for example during javax.jdo.PersistenceManager.flush or javax.jdo.Transaction.commit.(Method of javax.jdo.listener.StoreLifecycleListener)
postStore(event)
Invoked whenever a persistent instance is stored, for example during javax.jdo.PersistenceManager.flush or javax.jdo.Transaction.commit.(Method of javax.jdo.listener.StoreLifecycleListener)
preDelete(event)
Invoked whenever a persistent instance is deleted, for example during javax.jdo.PersistenceManager.deletePersistent.(Method of javax.jdo.listener.DeleteLifecycleListener)
postAttach(event)
This method is called after a detached instance is attached, via the javax.jdo.PersistenceManager.makePersistent method.(Method of javax.jdo.listener.AttachLifecycleListener)
postDelete(event)
Invoked whenever a persistent instance is deleted, for example during javax.jdo.PersistenceManager.deletePersistent.(Method of javax.jdo.listener.DeleteLifecycleListener)
