[Paul Ferraro (JIRA)]

Paul Ferraro updated JGRP-1177:
-------------------------------

    Attachment: patch.txt


Proposed patch expanding on the sample implementation with the following changes:
* Refactored pieces into separate classes with nicer names
* ScopedRpcDispatcher registers its scope with a ScopedUpHandler
* Added ScopeUpHandler deregistration on ScopedRpcDispatcher.stop().
* ScopedUpHandler accepts an optional default handler, which will be triggered for non-message events or messages with no scope header
* ScopedUpHandler returns NoHandlerForScope object if message is received for an unknown scope (e.g. its handler was not yet registered or was already deregistered)
* Automatically adds RspFilter to RequestOptions that rejects NoHandlerForScope responses, decorating any existing filter, if necessary.
* Added ScopedMessageDispatcher analogue

> Investigate sharing a channel between multiple components. Unlike the Multiplexer, this is light weight and doesn't require service views or other kludges !
> Attached is an example of how this could be implemented.
> This JIRA is only to investigate whether being able to share a channel between multiple components makes sense, or whether a shared transport is better suited. We do NOT want to re-create the Multiplexer, which to this day still haunts me !
