cMessage * RealworldApp::decapsulate	(	char *	buf,
		uint32_t	length
	)			[protected, virtual]

Parses data received from the tun device and converts it into a cMessage.

Parameters:

	buf	A pointer to the data to be parsed
	length	The length of the buffer in bytes

Returns:

The parsed message

Implements RealworldConnector.

{
    cMessage* payload = 0; 
    // "Decode" packet: 16bit payload length|payload
    payload = parser->decapsulatePayload( buf, length );
    if (!payload) {
        ev << "RealworldApp: Parsing of Payload failed, dropping packet.\n";
    }

    delete buf;
    return payload;
}

char * RealworldApp::encapsulate	(	cMessage *	msg,
		unsigned int *	length
	)			[protected, virtual]

Converts an IP datagram to a data block for sending it to the tun device.

Parameters:

	msg	A pointer to the message to be converted
	length	A pointer to an int that will hold the length of the converted data

Returns:

A pointer to the converted data

Implements RealworldConnector.

{
    unsigned int payloadLen;
    // parse payload
    char* payload = parser->encapsulatePayload(msg, &payloadLen);
    if (!payload )
        return NULL;

    if(payloadLen > 0xffff) {
        opp_error("RealworldApp: Encapsulating packet failed: packet too long");
    }
    *length = payloadLen;

    return payload;
}
