Example 1 with ConnectionHandler

use of io.reactivex.netty.channel.ConnectionHandler in project ribbon by Netflix.

the class HelloUdpServerExternalResource method start.

public void start() {
    int port;
    try {
        port = choosePort();
    } catch (SocketException e) {
        throw new RuntimeException("Error choosing point", e);
    }
    server = RxNetty.createUdpServer(port, new ConnectionHandler<DatagramPacket, DatagramPacket>() {

        @Override

            return newConnection.getInput().flatMap(new Func1<DatagramPacket, Observable<Void>>() {
