Package org.apache.commons.compress.compressors.snappy
package org.apache.commons.compress.compressors.snappy
Provides stream classes for the Snappy algorithm.
The raw Snappy format which only contains the compressed data
is supported by the SnappyCompressor*putStream
classes while the so called "framing format" is implemented
by FramedSnappyCompressor*putStream
. Note there
have been different versions of the framing format specification,
the implementation in Commons Compress is based on the
specification "Last revised: 2013-10-25".
Only the "framing format" can be auto-detected this means you
have to speficy the format explicitly if you want to read a
"raw" Snappy stream
via CompressorStreamFactory
.
