Method Detail

open

public static int open(IPAddress ipAddress,
                       int port,
                       NetworkInterface iface,
                       AddressFilter filter,
                       UDPDatagramHandler handler,
                       java.lang.String comManId,
                       boolean forceMulticastSocket)
                throws java.io.IOException

Opens a datagram socket for a given address and port.

This will start a new UDP listener for the given address and port. This listener will pass-through the incoming UDP datagram to the given UDP handler.

Parameters:

address - the address.

port - the port.

ifaceName -

handler - the UDP datagram handler which will handle the incoming UDP datagram.

Throws:

java.io.IOException - will throw an IO exception if the datagram socket could not be opened.

close

public static void close(IPAddress ipAddress,
                         int port,
                         NetworkInterface iface)
                  throws java.io.IOException

Closes the created UDP connection listener by address and port.

Parameters:

address - the address.

port - the port.

Throws:

java.io.IOException

send

public static void send(IPAddress localAddress,
                        int localPort,
                        NetworkInterface iface,
                        Datagram datagram)
                 throws java.io.IOException

Sends a datagram packet with the given address and port.

Parameters:

address - the source address.

localPort - the source port.

dstAddress - the destination address of the datagram packet.

dstPort - the destination port of the datagram packet.

data - the content of the datagram packet.

len - the length of the datagram packet.

Throws:

java.io.IOException

getDatagramSocket

public static DatagramSocket getDatagramSocket(IPAddress ipAddress,
                                               int port,
