Examples with RegistrationUpdateEvent io.vertx.core.spi.cluster.RegistrationUpdateEvent used on opensource projects

Example 1 with RegistrationUpdateEvent

use of io.vertx.core.spi.cluster.RegistrationUpdateEvent in project vert.x by eclipse.

the class ClusteredEventBusTest method testSendWriteHandler.

@Test
public void testSendWriteHandler() throws Exception {
    CountDownLatch updateLatch = new CountDownLatch(3);
    Supplier<VertxOptions> options = () -> getOptions().setClusterManager(new WrappedClusterManager(getClusterManager()) {

        @Override
        public void init(Vertx vertx, NodeSelector nodeSelector) {
            super.init(vertx, new WrappedNodeSelector(nodeSelector) {

                @Override
                public void registrationsUpdated(RegistrationUpdateEvent event) {
                    super.registrationsUpdated(event);
                    if (event.address().equals(ADDRESS1) && event.registrations().size() == 1) {
                        updateLatch.countDown();
                    }
                }

                @Override
                public boolean wantsUpdatesFor(String address) {
                    return true;
                }
            });
        }
    });
    startNodes(options.get(), options.get());
    waitFor(2);
    vertices[1].eventBus().consumer(ADDRESS1, msg -> complete()).completionHandler(onSuccess(v1 -> updateLatch.countDown()));
    awaitLatch(updateLatch);
    MessageProducer<String> producer = vertices[0].eventBus().sender(ADDRESS1);
    producer.write("body", onSuccess(v2 -> complete()));
    await();
}
