        public abstract void decompress​(DataInput in,
                                        int originalLength,
                                        int offset,
                                        int length,
                                        BytesRef bytes)
                                 throws IOException
        Decompress bytes that were stored between offsets offset and offset+length in the original stream from the compressed stream in to bytes . After returning, the length of bytes (bytes.length) must be equal to length. Implementations of this method are free to resize bytes depending on their needs.
        in - the input that stores the compressed stream
        originalLength - the length of the original data (before compression)
        offset - bytes before this offset do not need to be decompressed
        length - bytes after offset+length do not need to be decompressed
        bytes - a BytesRef where to store the decompressed data
