102 | isLoaded(entity, attributeName)Method javax.persistence.PersistenceUtil boolean isLoaded( Object entity, String attributeName ) Determine the load state of a given persistent attribute. Parameters: entity - entity containing the attribute attributeName - name of attribute whose load state is to be determined Returns: false |
102 | isLoaded(entity)Method javax.persistence.PersistenceUtil boolean isLoaded( Object entity ) Determine the load state of an entity.
