The following interfaces and enum types represent attributes (persistent fields and properties) in the JPA Metamodel API: See the Metamodel Attribute Interface Hierarchy section for more details and examples.

This reference contains the API documentation (similar to JavaDoc) of the Java Persistence API (JPA) 2.0. The content is derived from the original JPA documentation (in the EclipseLink JPA 2 RI) with some additions and notes. The JPA types are organized into the following sections: The purpose

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

This section contains miscellaneous JDO annotations and associated enum types :

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 way a field of a persistable class is managed by JDO can be set by the following annotations and enum types :
