| <P> |
| This interface is implemented by classes that can be detached from the |
| persistence context and later attached. The interface includes the |
| contract by which the StateManager can set the object id, version, |
| BitSet of loaded fields, and BitSet of modified fields |
| so they are preserved while outside the persistence environment. |
| <P>The detached state is stored as a field in each instance of Detachable. |
| The field is serialized so as to maintain the state of the instance |
| while detached. While detached, only the BitSet of modified fields |
| will be modified. The structure of the Object[] jdoDetachedState |
| is as follows: |
| <ul><li>jdoDetachedState[0]: the Object Id of the instance |
| </li><li>jdoDetachedState[1]: the Version of the instance |
| </li><li>jdoDetachedState[2]: a BitSet of loaded fields |
| </li><li>jdoDetachedState[3]: a BitSet of modified fields |
| </li></ul> |
