- (UDPSocket) udp_connect {|socket| ... } (protected)

Opens a UDP connection to the host and port specified by the host and port parameters. If the local_host and local_port parameters are set, they will be used for the local host and port of the UDP connection.

Examples:

udp_connect
# => UDPSocket
udp_connect do |socket|
  puts socket.readlines
end

Yields:

  • (socket) —

    If a block is given, it will be passed the newly created socket.

Yield Parameters:

  • socket (UDPsocket) —

    The newly created UDPSocket object.

Returns:

  • (UDPSocket) —

    The newly created UDPSocket object.

end

- (UDPSocket) udp_connect_and_send(data) {|socket| ... } (protected)

Connects to the host and port specified by the host and port parameters, then sends the given data. If the local_host and local_port instance methods are set, they will be used for the local host and port of the UDP connection.

Parameters:

  • data (String) —

    The data to send through the connection.

Yields:

  • (socket) —

    If a block is given, it will be passed the newly created socket.

end

- (Boolean?) udp_open?(timeout = nil) (protected)

Tests whether the UDP port, specified by the host and port parameters, is open.

Parameters:

  • timeout (Integer) (defaults to: nil) —

    (5) The maximum time to attempt connecting.

Returns:

  • (Boolean, nil) —

    Specifies whether the remote UDP port is open. If no data or ICMP error were received, nil will be returned.

end

- (nil) udp_recv {|server, (client_host, client_port), mesg| ... } (protected)

Creates a new UDPServer listening on the server_host and server_port parameters, accepts only one message from a client.

Examples:

udp_recv do |server,(host,port),mesg|
  server.send('hello',host,port)
end

Yields:

  • (server, (client_host, client_port), mesg) —

    The given block will be passed the client host/port and the received message.

    print_debug mesg

    yield server, [host, port], mesg if block_given?
  end

  print_info "Closed #{self.server_host_port}"
  return nil
end

- (true) udp_send(data) (protected)

Connects to the host and port specified by the host and port parameters, sends the given data and then disconnects.

Examples:

buffer = "GET /" + ('A' * 4096) + "\n\r"
udp_send(buffer)
# => true

Returns:

  • (true) —

    The data was successfully sent.
