Detailed Description

The following Transform constants can be used with TransformInputStream and TransformOutputStream to transform stream data

Example:: Qore::FileOutputStream of("my-file.txt");

Qore::TransformOutputStream ts(of, get_decompressor(Qore::COMPRESSION_ALG_BZIP2));

Qore::FileOutputStream
This class implements the OutputStream interface for writing bytes to a file.

Qore::COMPRESSION_ALG_BZIP2
const COMPRESSION_ALG_BZIP2
Identifies the bzip2 algorithm

Qore::get_decompressor
Transform get_decompressor(string alg)
Returns a Transform object for decompressing data using the given algorithm for use with TransformInp...

Qore::list
list< auto > list(...)
Returns a list of the arguments passed at the top level.

Variable Documentation

const Qore::COMPRESSION_ALG_BROTLI = str(CompressionTransforms::ALG_BROTLI)

Identifies the Brotli compression algorithm (RFC 7932)

const Qore::COMPRESSION_ALG_LZ4 = str(CompressionTransforms::ALG_LZ4)

Identifies the LZ4 compression algorithm.

Note: LZ4 does not store the original size in the compressed data, so decompression requires either a max_output_size parameter or knowledge of the original size.

const Qore::COMPRESSION_ALG_ZSTD = str(CompressionTransforms::ALG_ZSTD)

Identifies the Zstandard compression algorithm (RFC 8878)
