currentFrame()

const

Bytes of the just-completed frame (header + payload + CRC). Valid only immediately after addByte() returned true, before the next reset().

extractValidFrames()

QByteArray RTCMParser::extractValidFrames	(	const QByteArray &	in,
		int *	framesFound = nullptr,
		int *	framesDropped = nullptr
	)

Feed a buffer through the parser, carrying state across calls, and return the concatenation of every complete CRC-valid frame found. Whitelist filtering is NOT applied. Optionally reports frame counts for caller logging.
