From: Robert Varga Date: Fri, 23 Aug 2013 13:55:03 +0000 (+0200) Subject: BUG-58: refactor to take advantage of netty X-Git-Tag: jenkins-bgpcep-bulk-release-prepare-only-1~237^2~293 X-Git-Url: https://git.opendaylight.org/gerrit/gitweb?a=commitdiff_plain;h=a01e8a8629311b3480b2085aca40feea539f4ba0;p=bgpcep.git BUG-58: refactor to take advantage of netty This patchset reworks the framework to take advantage of features in netty, shortcutting many of the previous concepts. This lead to a major refactor, reorganizing the way things are glued together. SessionProposal/Checkers have been removed in favor of an explicit negotiation piece, which is put on the channel pipeline to negotiate session parameters -- uopn success it replaces itself with a complete session. ProtocolSessionInboundHandler has been integrated into AbstractProtocolSession, handling the tasks normally. Finally, Dispatcher uses all this restructure to implement Session reconnect in a relatively straightforward manner.
