<body>
<p>Provides stream classes for the
<a href="http://lz4.github.io/lz4/">LZ4</a>
algorithm.</p>
<p>The block LZ4 format which only contains the compressed data is
supported by the <code>BlockLZ4Compressor*putStream</code>
classes while the frame format is implemented
by <code>FramedLZ4Compressor*putStream</code>. 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.</p>
<p>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 <code>CompressorStreamFactory</code>.</p>
