All Implemented Interfaces:
ExceptionListener, Disposable, UMOConnectable, UMOMessageDispatcher, UMOMessageDispatching

public class StreamMessageDispatcher
extends AbstractMessageDispatcher

StreamMessageDispatcher is a simple stream dispatcher that obtains a stream from the Stream Connector to write to. This is only really useful for testing purposes right now when writing to System.in and System.out. However, it is feasible to set any OutputStream on the Stream connector and have that written to.
