messif.objects.nio.SingleClassSerializator<T>
T
- the class of objects created by this serializator during deserializationpublic class SingleClassSerializator<T>
This is the simple serializator implementation for BinarySerializable
objects.
It can store and restore only one specified class or the standard Java-serialized objects.
