      • isLoaded

        public boolean isLoaded​(java.lang.Object entity)
        Description copied from interface: PersistenceUtil
        Determine the load state of an entity. This method can be used to determine the load state of an entity passed as a reference. An entity is considered loaded if all attributes for which FetchType.EAGER has been specified have been loaded.

        The isLoaded(Object, String) method should be used to determine the load state of an attribute. Not doing so might lead to unintended loading of state.

        Specified by:
        isLoaded in interface PersistenceUtil
        Parameters:
        entity - whose load state is to be determined
        Returns:
        false if the entity has not been loaded, else true
