This is a hint and is disregarded for primitive types; it may be used in schema generation. If not specified, defaults to true. Default value: true Since: JPA 1.0 |
0 | jdoIsTransactional()Method javax.jdo.spi.PersistenceCapable boolean jdoIsTransactional() Tests whether this object is transactional. Instances whose state is associated with the current transaction return true. Transient instances return false. Returns: true if this instance is transactional. Since: JDO 1.0 |
0 | javax.jdo.identity.IntIdentity Returns: true if both objects represent the same object id Since: JDO 1.0 boolean equals(Object obj ... - the other object Returns: true if the class or class name is the same Since: JDO 1.0 int getKey() Return the key |
0 | isDirty(pc) transaction return true. Transient nontransactional instances return false. Parameters: pc - the calling PersistenceCapable instance Returns: true if this instance has been modified in the current |
0 | isNew(pc) return true. Transient instances return false. Parameters: pc - the calling PersistenceCapable instance Returns: true if this instance was made persistent in the current transaction. Since: JDO 1.0 See Also: PersistenceManager.makePersistent(Object pc) |
0 | isPersistent(pc) Boolean.TRUE. Instances known by the implementation to be non-persistent return Boolean.FALSE. Instances ... .TRUE if the parameter instance is persistent. Since: JDO 2.0 See Also: PersistenceManager.makePersistent(Object pc) PersistenceCapable.jdoIsPersistent() |
0 | isNew(pc) transaction return Boolean.TRUE. Instances known by the implementation to be non-new return Boolean.FALSE ... : Boolean.TRUE if the parameter instance was made persistent in the current transaction. Since: JDO 2 |

0 | isDeleted(pc)Method javax.jdo.spi.StateManager boolean isDeleted( PersistenceCapable pc ) Tests whether this object has been deleted. Instances that have been deleted in the current transaction return true. Transient instances return false. Parameters: pc - the calling PersistenceCapable instance Returns: true |
