Bela Ban commented on JGRP-1193:
--------------------------------
Re Brian's last point: we cannot mark a response as received if the filter rejects it
because GET_FIRST would fail in this case:
- We expect responses from 3 members
- The first response is null, NonNullResponseFilter rejects it
- However, if we set received=true, the call will return because num_received >= 1 !
Simplify RspFilter interface

Key: JGRP-1193
URL: https://issues.jboss.org/browse/JGRP-1193
Project: JGroups
Issue Type: Task
Affects Versions: 2.7, 2.8, 2.9
Reporter: Vladimir Blagojevic
Assignee: Vladimir Blagojevic
Fix For: 3.0
RspFilter interface although having only two methods in its contract has been a source of
some confusion regarding the semantics of response filtering. In order to simplify and
make response filtering semantics easier to understand and implement a new RspFilter has
been proposed for 3.0.
RspFilterResult responseReceived(Object response, Address sender);
RspFilterResult is an enum with four states where each state is essentially a combination
of two boolean variables: validResponse and needMoreResponses.
