The following types can be used to implement external listener classes for JDO lifecycle events: Listener objects can be bound to one or more persistence capable classes by invoking the addInstanceLifecycleListner method either at the PersistenceManagerFactory level or the PersistenceManager level.

The following annotations can mark methods as JPA callback methods: The Lifecycle Events section of the ObjectDB Manual explains how to use all these annotations on callback methods and with listener classes.

JPA defines three types of persistable classes which are set by the following annotations: Chapter 2 of the ObjectDB manual explains these annotations in detail. Entity and mapped super classes can be further configured by annotations that specify cache preferences and lifecycle event listener
