    • IntRiceCompressor

      public IntRiceCompressor(RiceCompressOption option)

  • Method Details

    • compress

      public boolean compress(IntBuffer buffer, ByteBuffer writeBuffer)
      Description copied from interface: ICompressor
      compress the buffer into the byte buffer. Attention enough space must already be allocated.
      Parameters:
      buffer - the buffer to compress.
      writeBuffer - the compressed data
      Returns:
      true if the compression succeeded.

    • decompress

      public void decompress(ByteBuffer readBuffer, IntBuffer buffer)
      Description copied from interface: ICompressor
      Decompress the byte buffer and restore the buffer from it, again enough space must already be allocated.
      Parameters:
      readBuffer - the compressed data
      buffer - the buffer to fill with the uncompressed data.
