 /**
 24  
  * <code>StdioMessageDispatcher</code> is a simple stream dispatcher that obtains
 25  
  * a stream from the Stream Connector to write to. This is only really useful for
 26  
  * testing purposes right now when writing to System.in and System.out. However, it
 27  
  * is feasible to set any OutputStream on the Stream connector and have that written
 28  
  * to.
