| * <B>Keywords:</B> serialize detach <br> |
| * <B>Assertion IDs:</B> A12.6.8-4, A12.6.8-5 <br> |
| * <B>Assertion Description: </B> The JDO 1.0 specification requires that serialized instances be |
| * made ready for serialization by instantiating all serializable persistent fields before calling |
| * writeObject. For binary- compatible implementations, this is done by the enhancer adding a call |
| * to the StateManager prior to invoking the user's writeObject method. The behavior is the same in |
| * JDO 2.0, with the additional requirement that restored detachable serialized instances are |
| * treated as detached instances. |
