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