Examples with DatagramPacket java.net.DatagramPacket used on opensource projects

Example 61 with DatagramPacket

use of java.net.DatagramPacket in project routerkeygenAndroid by routerkeygen.

the class AlcatelLucentKeygen method sendQuery.

private static void sendQuery(DNSQuery dnsquery, DatagramSocket datagramsocket, InetAddress inetaddress) throws IOException {
    final byte[] query = dnsquery.extractQuery();
    datagramsocket.send(new DatagramPacket(query, query.length, inetaddress, 5353));
}

Example 62 with DatagramPacket

use of java.net.DatagramPacket in project robovm by robovm.

the class PlainDatagramSocketImpl method peek.

@Override
protected int peek(InetAddress sender) throws IOException {
    // We don't actually want the data: we just want the DatagramPacket's filled-in address.
    DatagramPacket packet = new DatagramPacket(EmptyArray.BYTE, 0);
    int result = peekData(packet);
    // Note: evil side-effect on InetAddress! This method should have returned InetSocketAddress!
    sender.ipaddress = packet.getAddress().getAddress();
    return result;
}

Example 63 with DatagramPacket

use of java.net.DatagramPacket in project robovm by robovm.

the class DatagramChannelImpl method receiveDirectImpl.

private SocketAddress receiveDirectImpl(ByteBuffer target, boolean loop) throws IOException {
    SocketAddress retAddr = null;
    DatagramPacket receivePacket = new DatagramPacket(EmptyArray.BYTE, 0);
    int oldposition = target.position();
    int received = 0;
    do {
        received = IoBridge.recvfrom(false, fd, target, 0, receivePacket, isConnected());
        if (receivePacket != null && receivePacket.getAddress() != null) {
            // copy the data of received packet
            if (received > 0) {
                target.position(oldposition + received);
            }
            retAddr = receivePacket.getSocketAddress();
            break;
        }
    } while (loop);
    return retAddr;
}
