Examples with EventBus io.vertx.core.eventbus.EventBus used on opensource projects

Example 11 with EventBus

use of io.vertx.core.eventbus.EventBus in project vert.x by eclipse.

the class EventBusExamples method example14.

public void example14() {
    VertxOptions options = new VertxOptions().setEventBusOptions(new EventBusOptions().setClusterPublicHost("whatever").setClusterPublicPort(1234));
    Vertx.clusteredVertx(options, res -> {
        if (res.succeeded()) {
            Vertx vertx = res.result();
            EventBus eventBus = vertx.eventBus();
            System.out.println("We now have a clustered event bus: " + eventBus);
        } else {
            System.out.println("Failed: " + res.cause());
        }
    });
}

Example 12 with EventBus

use of io.vertx.core.eventbus.EventBus in project vert.x by eclipse.

the class EventBusExamples method example2.

public void example2(Vertx vertx) {
    EventBus eb = vertx.eventBus();
    MessageConsumer<String> consumer = eb.consumer("news.uk.sport");
    consumer.handler(message -> {
        System.out.println("I have received a message: " + message.body());
    });
}

Example 13 with EventBus

use of io.vertx.core.eventbus.EventBus in project vert.x by eclipse.

the class MetricsTest method testReplyFailureRecipientFailure.

@Test
public void testReplyFailureRecipientFailure() throws Exception {
    CountDownLatch latch = new CountDownLatch(1);
    EventBus eb = vertx.eventBus();
    FakeEventBusMetrics metrics = FakeMetricsBase.getMetrics(eb);
    AtomicReference<String> replyAddress = new AtomicReference<>();
    CountDownLatch regLatch = new CountDownLatch(1);
    eb.consumer("foo", msg -> {
        replyAddress.set(msg.replyAddress());
        msg.fail(0, "whatever");
    }).completionHandler(onSuccess(v -> {
        regLatch.countDown();
    }));
    awaitLatch(regLatch);
    eb.send("foo", "bar", new DeliveryOptions(), ar -> {
        assertTrue(ar.failed());
        latch.countDown();
    });
    awaitLatch(latch);
    assertEquals(Collections.singletonList(replyAddress.get()), metrics.getReplyFailureAddresses());
    assertEquals(Collections.singletonList(ReplyFailure.RECIPIENT_FAILURE), metrics.getReplyFailures());
}

Example 14 with EventBus

use of io.vertx.core.eventbus.EventBus in project vert.x by eclipse.

the class MetricsTest method testReplyFailureNoHandlers.

@Test
public void testReplyFailureNoHandlers() throws Exception {
    CountDownLatch latch = new CountDownLatch(1);
    EventBus eb = vertx.eventBus();
    eb.send(ADDRESS1, "bar", new DeliveryOptions().setSendTimeout(10), ar -> {
        assertTrue(ar.failed());
        latch.countDown();
    });
    awaitLatch(latch);
    FakeEventBusMetrics metrics = FakeMetricsBase.getMetrics(eb);
    assertEquals(Collections.singletonList(ADDRESS1), metrics.getReplyFailureAddresses());
    assertEquals(Collections.singletonList(ReplyFailure.NO_HANDLERS), metrics.getReplyFailures());
}

Example 15 with EventBus

use of io.vertx.core.eventbus.EventBus in project vert.x by eclipse.

the class MetricsContextTest method testEventBusLifecycle.

@Test
public void testEventBusLifecycle() {
    AtomicBoolean closeCalled = new AtomicBoolean();
    VertxMetricsFactory factory = (vertx, options) -> new DummyVertxMetrics() {

        @Override
        public EventBusMetrics createMetrics(EventBus eventBus) {
            return new DummyEventBusMetrics() {

                @Override
                public boolean isEnabled() {
                    return true;
                }

                @Override
                public void close() {
                    closeCalled.set(true);
                }
            };
        }
    };
    Vertx vertx = vertx(new VertxOptions().setMetricsOptions(new MetricsOptions().setEnabled(true).setFactory(factory)));
    vertx.eventBus();
    executeInVanillaThread(() -> {
        vertx.close(onSuccess(v -> {
            assertTrue(closeCalled.get());
            testComplete();
        }));
    });
    await();
