public class Unserializer

extends Reviver

Safe: Used to specialize the UnserializationStream for reviving from state serialized using a corresponding Serializer, where this reviving uses no magic authority.

Therefore, we declare the class Unserializer to be safe.

Unserializer is specializable from E by providing a reviveFunc so that, on reincarnating for example, a restored object may be revives as a different object to be checkpointed as its representative.
