                                                BytePointer output)

\brief Decompress some input. If need_more_output is true on return, a larger output buffer needs to be supplied.

Decompress

@ByVal
public DecompressResultResult Decompress(@Cast(value="int64_t")
                                                long input_len,
                                                @Cast(value="const uint8_t*")
                                                byte[] input,
                                                @Cast(value="int64_t")

                                                byte[] output)

IsFinished

@Cast(value="bool")
public boolean IsFinished()

\brief Return whether the compressed stream is finished. This is a heuristic. If true is returned, then it is guaranteed that the stream is finished. If false is returned, however, it may simply be that the underlying library isn't able to provide the information.

Reset

@ByVal
public Status Reset()

\brief Reinitialize decompressor, making it ready for a new compressed stream.
