Member Function Documentation

unsigned long pcl::AdaptiveRangeCoder::decodeStreamToCharVector	(	std::istream &	inputByteStream_arg,
		std::vector< char > &	outputByteVector_arg
	)

Decode char stream to output vector.

Parameters:

inputByteStream_arg	input stream of compressed data
outputByteVector_arg	decompressed output vector

Returns:

amount of bytes read from input stream

Definition at line 143 of file entropy_range_coder.hpp.

unsigned long pcl::AdaptiveRangeCoder::encodeCharVectorToStream	(	const std::vector< char > &	inputByteVector_arg,
		std::ostream &	outputByteStream_arg
	)

Encode char vector to output stream.

Parameters:

inputByteVector_arg	input vector
outputByteStream_arg	output stream containing compressed data

Returns:

amount of bytes written to output stream
