Class TransactionScopedEntityManager

java.lang.Object

org.jboss.as.jpa.container.AbstractEntityManager

org.jboss.as.jpa.container.TransactionScopedEntityManager

All Implemented Interfaces:

Serializable, javax.persistence.EntityManager

public class TransactionScopedEntityManager
extends AbstractEntityManager
implements Serializable

Transaction scoped entity manager will be injected into SLSB or SFSB beans. At bean invocation time, they will join the active transaction if one is present. Otherwise, they will simply be cleared at the end of the bean invocation.

This is a proxy for the underlying persistent provider EntityManager.
