All Superinterfaces:
javax.persistence.EntityManager

public interface EntityManagerProxy
extends javax.persistence.EntityManager

javax.persistence.EntityManager getTargetEntityManager()
                                                       throws java.lang.IllegalStateException
Return the underlying EntityManager that this proxy will delegate to.

In case of an extended EntityManager, this will be the associated raw EntityManager.

In case of a shared ("transactional") EntityManager, this will be the raw EntityManager that is currently associated with the transaction. Outside of a transaction, an IllegalStateException will be thrown.

Returns:
the underlying raw EntityManager (never null)
Throws:
java.lang.IllegalStateException - if no underlying EntityManager is available
