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

Example 6 with Message

use of io.vertx.core.eventbus.Message in project vertx-examples by vert-x3.

the class Consume method start.

@Suspendable
@Override
public void start() throws Exception {
    EventBus eb = vertx.eventBus();
    // Create a couple of consumers on different addresses
    // The adaptor allows handler to be used as a Channel
    HandlerReceiverAdaptor<Message<String>> adaptor1 = streamAdaptor();
    eb.<String>consumer(ADDRESS1).handler(adaptor1);
    HandlerReceiverAdaptor<Message<String>> adaptor2 = streamAdaptor();
    eb.<String>consumer(ADDRESS2).handler(adaptor2);
    // Set up a periodic timer to send messages to these addresses
    vertx.setPeriodic(500, tid -> {
        eb.send(ADDRESS1, "wibble");
        eb.send(ADDRESS2, "flibble");
    });
    // This runs on an event loop but the event loop is at no time blocked!
    for (int i = 0; i < 10; i++) {
        System.out.println("Thread is " + Thread.currentThread());
        Message<String> received1 = adaptor1.receive();
        System.out.println("got message: " + received1.body());
        Message<String> received2 = adaptor2.receive();
        System.out.println("got message: " + received2.body());
    }
}
