| Class | Description | 
|---|---|
| BlockLZ4CompressorInputStream | CompressorInputStream for the LZ4 block format. | 
| BlockLZ4CompressorOutputStream | CompressorOutputStream for the LZ4 block format. | 
| FramedLZ4CompressorInputStream | CompressorInputStream for the LZ4 frame format. | 
| FramedLZ4CompressorOutputStream | CompressorOutputStream for the LZ4 frame format. | 
| FramedLZ4CompressorOutputStream.Parameters | Parameters of the LZ4 frame format. | 
| XXHash32 | Implementation of the xxhash32 hash algorithm. | 
| Enum | Description | 
|---|---|
| FramedLZ4CompressorOutputStream.BlockSize | The block sizes supported by the format. | 
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.
