| /** |
| * This class allows an object to validate that it is valid after |
| * deserialization has run completely for it and all dependent objects. |
| * This allows an object to determine if it is invalid even if all |
| * state data was correctly deserialized from the stream. It can also |
| * be used to perform re-initialization type activities on an object |
| * after it has been completely deserialized. |
| * |
| * Since this method functions as a type of callback, it must be |
| * registered through <code>ObjectInputStream.registerValidation</code> |
| * in order to be invoked. This is typically done in the |
| * <code>readObject</code> method. |
