| /** |
| * 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>jdoDetachedState[1]: the Version of the instance |
| * <li>jdoDetachedState[2]: a BitSet of loaded fields |
| * <li>jdoDetachedState[3]: a BitSet of modified fields |
| * </ul> |
