Constructor & Destructor Documentation

◆ DataPacket()

DataPacket::DataPacket ( )

Double check that packet struct is correct length. Watch out for RTTI increasing the size.

◆ getBytestream()

char * DataPacket::getBytestream	(	unsigned	bytestreamNumber,
		unsigned &	byteCount
	)

Verify that packet is correct type

Check bytestreamNumber in bounds

Calc positions in packet

Sum size of preceding stream buffers to get position

Double check buffer is completely within packet

Return start of buffer

◆ getBytestreamBufferLength()

unsigned DataPacket::getBytestreamBufferLength ( unsigned bytestreamNumber )

References getBytestream().

◆ verify()

void DataPacket::verify ( unsigned bufferLength = 0 ) const

Verify header is good

Calc sum of lengths of each bytestream buffer in this packet

Calc size of packet needed

If needed is not with 3 bytes of actual packet size, have an error

Verify that padding at end of packet is zero
