Package javax.jdo.listener Description

This package contains the JDO specification listener interfaces and classes.

There are two kinds of interfaces defined to allow an application to manage life cycle changes to persistent objects.

The first kind is defined on the persistent domain class itself. This allows methods in the domain class to be called during life cycle events. The domain class implements one or more of the interfaces AttachCallback, ClearCallback, DeleteCallback, DetachCallback, LoadCallback, or StoreCallback. The methods in the interfaces are called during life cycle events.

The second kind is defined on an external class using the listener pattern. Instances of classes that implement one or more of the listener interfaces AttachLifecycleListener, ClearLifecycleListener, CreateLifecycleListener, DeleteLifecycleListener, DetachLifecycleListener, DirtyLifecycleListener, LoadLifecycleListener, or StoreLifecycleListener are registered with the PersistenceManager or PersistenceManagerFactory and receive callbacks during life cycle events of the persistent instances of interest.
