public abstract class MarshallerObjectInputStream
extends java.io.ObjectInputStream
implements ByteInput

A marshaller's object input stream. Used by marshallers for compatibility with Java serialization. Instances of this class may be passed in to the overridden serialization methods for a class implementing Serializable.

This class is not part of the marshalling API; rather it is intended for marshaller implementers to make it easier to develop Java serialization-compatible marshallers.
