107This class provides CompressionOutputStream and CompressionInputStream for
108 compression and decompression. Currently we dont have an implementation of
109 the Compressor and Decompressor interfaces, so those methods of
110 CompressionCodec which have a Compressor or Decompressor type argument, throw
111 UnsupportedOperationException.
