Package org.apache.commons.compress.compressors.lz4 Description

Provides stream classes for the LZ4 algorithm.

The block LZ4 format which only contains the compressed data is supported by the BlockLZ4Compressor*putStream classes while the frame format is implemented by FramedLZ4Compressor*putStream. The implementation in Commons Compress is based on the specifications "Last revised: 2015-03-26" for the block format and version "1.5.1 (31/03/2015)" for the frame format.

Only the frame format can be auto-detected this means you have to speficy the format explicitly if you want to read a block LZ4 stream via CompressorStreamFactory.
