Detailed Description

C++ I/O stream wrappers to compress/decompress data on-the-fly.

CCompressIStream - input compression stream. CCompressOStream - output compression stream. CDecompressIStream - input decompression stream. CDecompressOStream - output decompression stream.

Compression/decompression manipulators: MCompress_BZip2, MDecompress_BZip2 MCompress_LZO, MDecompress_LZO MCompress_Zip, MDecompress_Zip MCompress_GZipFile, MDecompress_GZipFile, MDecompress_ConcatenatedGZipFile MCompress_ZipCloudflare, MDecompress_ZipCloudflare MCompress_GZipCloudflareFile, MDecompress_GZipCloudflareFile, MCompress_Zstd, MDecompress_Zstd

Note

The stream wrappers and manipulators doesn't support setting advanced compression parameters or using dictionaries. You neeed to create stream using algorithm-specific stream processor and tune up all necessary parameters there. See 'stream.hpp': CCompression[IO]Stream.
