Method Detail

executeUpdate

public Session executeUpdate(ServiceFactory sf,
                             Session session,
                             java.lang.String uuid,
                             long userId,
                             java.lang.Long sudoerId)

Specified by:

executeUpdate in interface SessionProvider

executeCloseSession

public void executeCloseSession(java.lang.String uuid)

Description copied from interface: SessionProvider

Loads a session directly, sets its "closed" value and immediately saves it. This method is not called directly from the SessionManager.close(String) and SessionManager.closeAll() methods since there are other non-explicit ways for a session to be destroyed, such as a timeout within SessionCache and so this is called from SessionManagerImpl.onApplicationEvent(org.springframework.context.ApplicationEvent) when a DestroySessionMessage is received.

Specified by:

executeCloseSession in interface SessionProvider
