close

public void close()

Description copied from interface: EntityManager

Close an application-managed entity manager. After the close method has been invoked, all methods on the EntityManager instance and any Query and TypedQuery objects obtained from it will throw the IllegalStateException except for getProperties, getTransaction, and isOpen (which will return false). If this method is called when the entity manager is associated with an active transaction, the persistence context remains managed until the transaction completes.

Specified by:

close in interface EntityManager

isOpen

public boolean isOpen()

Description copied from interface: EntityManager

Determine whether the entity manager is open.

Specified by:

isOpen in interface EntityManager

Returns:

true until the entity manager has been closed

shouldAutoCloseSession

public boolean shouldAutoCloseSession()

Description copied from interface: SessionOwner

Should session automatically be closed after transaction completion?

Specified by:

shouldAutoCloseSession in interface SessionOwner

Returns:

true/false appropriately.
