virtual cMessage* PacketParser::decapsulatePayload	(	char *	buf,
		unsigned int	length
	)			[pure virtual]

Parses a block of data received from the tun device.

Pure virtual function, has to be implemented by inherited classes.

Parameters:

	buf	The data to be parsed
	length	The length of the data

Returns:

A cMessage containing the parsed data

Implemented in RealWorldTestPacketParser, and GenericPacketParser.

virtual char* PacketParser::encapsulatePayload	(	cMessage *	msg,
		unsigned int *	length
	)			[pure virtual]

Parameters:

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

Returns:

A pointer to the converted data

Implemented in RealWorldTestPacketParser, and GenericPacketParser.
