org.jboss.seam.persistence.PersistenceProvider
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 ;-) @author Gavin King @author Pete Muir
