                throws java.io.IOException
        Description copied from class: Decompressor
        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.
        Specified by:
        decompress in class Decompressor
        Parameters:
        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
        Throws:
        java.io.IOException
