Class net.kuujo.vertigo.network.NetworkConfig

Examples of net.kuujo.vertigo.network.NetworkConfig.createConnection()

net.kuujo.vertigo.network.NetworkConfig.createConnection()
Creates a connection between two components. @param connection The new connection. @return The connection instance.

          // We can create four instances of the "receiver" and Vertigo will still
          // ensure that each file is sent to the same "receiver" instance.
          network.addVerticle("receiver", FileReceiver.class.getName(), 4);


          // Create a connection between "sender" and "receiver" via the "file" port.
          network.createConnection("sender", "file", "receiver", "file");


          // Now deploy the network to the cluster.
          Cluster cluster = result.result();
          cluster.deployNetwork(network, new Handler<AsyncResult<ActiveNetwork>>() {
