org.jboss.seam.persistence
Class DefaultPersistenceProvider

java.lang.Object
  org.jboss.seam.persistence.DefaultPersistenceProvider

All Implemented Interfaces:

Serializable, org.jboss.seam.persistence.SeamPersistenceProvider

Direct Known Subclasses:

HibernatePersistenceProvider

public class DefaultPersistenceProvider
extends Object
implements org.jboss.seam.persistence.SeamPersistenceProvider, Serializable

Abstraction layer for persistence providers (JPA implementations). This class provides a working base implementation that can be optimized for performance and non-standardized features by extending and overriding the methods.

The methods on this class are a great todo list for the next rev of the JPA spec ;-)
