Re: [infinispan-dev] XSite route status listener in server - ISPN-7230/ISPN-7231

Hi Galder, Sorry for the delay. For server-mode, we'd need to set the RouteStatusListener in the jgroups subsystem before the RELAY2 protocol is initialized. e.g. public class DefaultRouteStatusListener implements RouteStatusListener, Supplier<Set<String>> { private final Set<String> view = new ConcurrentSkipListSet<>(); @Override public void sitesUp(String... sites) { this.view.addAll(Arrays.asList(sites)); log.receivedXSiteClusterView(view); } @Override public void sitesDown(String... sites) { this.view.removeAll(Arrays.asList(sites)); log.receivedXSiteClusterView(view); } @Override public Set<String> get() { return Collections.unmodifiableSet(this.view); } } We would set the RouteStatusListener following this line from JChannelFactory: https://github.com/infinispan/infinispan/blob/master/server/integration/j... e.g. RELAY2 relay = new RELAY2().site(localSite); relay.setRouteStatusListener(new DefaultRouteStatusListener()); JGroupsTransport can then obtain the site view via: @Override public Set<String> getSitesView() { RELAY2 relay = channel.getProtocolStack().findProtocol(RELAY2.class); RouteStatusListener listener = (relay != null) ? relay.getRouteStatusListener() : null; return (listener instanceof Supplier) ? ((Supplier<Set<String>>) listener).get() : null; } On Thu, Jan 12, 2017 at 6:10 AM, Galder Zamarreño <galder(a)redhat.com&gt; wrote:
