      • getActiveSession

        Session getActiveSession()
        This method returns the current session to the requester. The current session will be the active UnitOfWork within a transaction and will be a 'scrap' UnitOfWork outside of a transaction. The caller is concerned about the results then the getSession() or getUnitOfWork() API should be called.
      • getAbstractSession

        org.eclipse.persistence.internal.sessions.AbstractSession getAbstractSession()
        Return the underlying database session
      • getDatabaseSession

        org.eclipse.persistence.internal.sessions.DatabaseSessionImpl getDatabaseSession()
        Return the underlying database session
      • getServerSession

        ServerSession getServerSession()
        Return the underlying server session

        SessionBroker getSessionBroker()
        Return the underlying session broker
      • getMemberDatabaseSession

        org.eclipse.persistence.internal.sessions.AbstractSession getMemberDatabaseSession​(java.lang.Class cls)
        Return the member DatabaseSessionImpl that maps cls in session broker. Return null if either not a session broker or cls is not mapped. Session broker implement composite persistence unit.
      • getMemberServerSession

        ServerSession getMemberServerSession​(java.lang.Class cls)
        Return the member ServerSession that maps cls in session broker. Return null if either not a session broker or cls is not mapped. Session broker implement composite persistence unit.
      • getMemberSessionName

        java.lang.String getMemberSessionName​(java.lang.Class cls)
        Return the name of member session that maps cls. Return null if either not a session broker or cls is not mapped. Session broker implement composite persistence unit.
      • isBroker

        boolean isBroker()
        Indicates whether the underlying session is a session broker. Session broker implement composite persistence unit.
