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.

Method Detail

getEntityManager

protected javax.persistence.EntityManager getEntityManager()

Specified by:

getEntityManager in class AbstractEntityManager

isExtendedPersistenceContext

protected boolean isExtendedPersistenceContext()

Specified by:

isExtendedPersistenceContext in class AbstractEntityManager

Returns:

true if an extended persistence context is in use

Precondition: getEntityManager() must be called previous to calling isExtendedPersistenceContext

isInTx

protected boolean isInTx()

Specified by:

isInTx in class AbstractEntityManager

Returns:

true if a JTA transaction is active

Precondition: getEntityManager() must be called previous to calling isInTx

close

public void close()

Catch the application trying to close the container managed entity manager and throw an IllegalStateException

Specified by:

close in interface javax.persistence.EntityManager

Overrides:

close in class AbstractEntityManager

getSynchronizationType

public javax.persistence.SynchronizationType getSynchronizationType()

Specified by:

getSynchronizationType in class AbstractEntityManager

deferEntityDetachUntilClose

protected boolean deferEntityDetachUntilClose()

return true if non-tx invocations should defer detaching of entities until entity manager is closed. Note that this is an extension for compatibility with JBoss application server 5.0/6.0 (see AS7-2781)

Specified by:

deferEntityDetachUntilClose in class AbstractEntityManager
