Class StyxInterloper

java.lang.Object
  uk.ac.rdg.resc.jstyx.interloper.StyxInterloper

All Implemented Interfaces:

InterloperListener

Direct Known Subclasses:

StyxMon

public class StyxInterloper
extends java.lang.Object
implements InterloperListener

A StyxInterloper listens for Styx messages, then forwards them directly to another Styx server. The replies from the other Styx server are sent back to the client. This allows the Styx messages sent between systems to be investigated.
