0 | PersistenceCapable.READ_WRITE_OKStatic Field javax.jdo.spi.PersistenceCapable byte READ_WRITE_OK If jdoFlags is set to READ_WRITE_OK, then the fields in the default fetch group can be accessed for read or write without notifying the StateManager. Since: JDO 1.0 |
0 | jdoNewObjectIdInstance(o): the field value is fetched from the ObjectIdFieldSupplier and passed to the single field identity |
0 | newObjectIdInstance(pcClass, obj) constructor ObjectIdFieldSupplier: the field value is fetched from the ObjectIdFieldSupplier and passed |
