Method Detail

### read

    public IncomingDatagramMessage read(InetAddress receivedOnAddress,
                                        DatagramPacket datagram)
                                 throws UnsupportedDataException

  Description copied from interface: `DatagramProcessor`
  Reads the datagram and instantiates a message.

  The message is either a `UpnpRequest` or a `UpnpResponse` operation type.

  Specified by:
    `read` in interface `DatagramProcessor`
  Parameters:
    `receivedOnAddress` - The address of the socket on which this datagram was received.
    `datagram` - The received UDP datagram.
  Returns:
    The populated instance.
  Throws:
    `UnsupportedDataException` - If the datagram could not be read, or didn't contain required data.

### write

    public DatagramPacket write(OutgoingDatagramMessage message)
                         throws UnsupportedDataException

  Description copied from interface: `DatagramProcessor`
  Creates a UDP datagram with the content of a message.

  The outgoing message might be a `UpnpRequest` or a `UpnpResponse`.

  Specified by:
    `write` in interface `DatagramProcessor`
  Parameters:
    `message` - The outgoing datagram message.
  Returns:
    An actual UDP datagram.
  Throws:
    `UnsupportedDataException` - If the datagram could not be created.

### readRequestMessage

    protected IncomingDatagramMessage readRequestMessage(InetAddress receivedOnAddress,
                                                         DatagramPacket datagram,
                                                         ByteArrayInputStream is,
                                                         String requestMethod,
                                                         String httpProtocol)

  Throws:
    `Exception`

### readResponseMessage

    protected IncomingDatagramMessage readResponseMessage(InetAddress receivedOnAddress,
                                                          DatagramPacket datagram,
                                                          ByteArrayInputStream is,
