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. * * @author Aaron M.
