Interface EntityManagerProxy

All Superinterfaces:
AutoCloseable, jakarta.persistence.EntityManager
public interface EntityManagerProxy extends jakarta.persistence.EntityManager
Subinterface of EntityManager to be implemented by EntityManager proxies. Allows access to the underlying target EntityManager.

This interface is mainly intended for framework usage. Application code should prefer the use of the EntityManager.getDelegate() method to access native functionality of the underlying resource.

    • getTargetEntityManager

      jakarta.persistence.EntityManager getTargetEntityManager() throws 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 a transaction, an IllegalStateException will be thrown.

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