Detailed Description

Interface for private data of transformations.

Member Function Documentation

virtual std::pair< int64, int64 > Transform::apply	(	const void *	src,
		int64	srcLen,
		void *	dst,
		int64	dstLen,
		ExceptionSink *	xsink
	)

pure virtual

Applies the transformation.

Parameters

src	pointer to source data or nullptr for flushing when no more input data is available
srcLen	the number of bytes in the src buffer
dst	pointer to destination buffer
dstLen	the number of bytes that can be written to dst
xsink	the exception sink

Returns: a pair (rc, wc) where rc is the number of bytes read from src and wc is the number of bytes written to dst
