public class AtomicMarshalOutputStream
extends MarshalOutputStream

This AtomicMarshalOutputStream, replaces a number of Java Object's in the stream with Serializer's that ordinarily would not be deserializable by AtomicMarshalInputStream or would not be safe to be deserialized, this includes, but is not limited to Java Collections classes, Throwable subclasses and object versions of primitive values.

Overrides:

IOException

reset

public void reset()
           throws IOException

Reset will disregard the state of any objects already written to the stream. The state is reset to be the same as a new ObjectOutputStream. The current point in the stream is marked as reset so the corresponding ObjectInputStream will be reset at the same point. Objects previously written to the stream will not be referred to as already being in the stream. They will be written to the stream again.

Overrides:

reset in class ObjectOutputStream

Throws:

IOException - if reset() is invoked while serializing an object.

                        throws IOException

Overrides:

defaultWriteObject in class ObjectOutputStream

Throws:
