    • compress

      void compress(int[] in, IntWrapper inpos, int inlength, byte[] out, IntWrapper outpos)
      Compress data from an array to another array. Both inpos and outpos are modified to represent how much data was read and written to if 12 ints (inlength = 12) are compressed to 3 bytes, then inpos will be incremented by 12 while outpos will be incremented by 3 we use IntWrapper to pass the values by reference.
      Parameters:
      in - input array
      inpos - location in the input array
      inlength - how many integers to compress
      out - output array
      outpos - where to write in the output array
    • uncompress

      void uncompress(byte[] in, IntWrapper inpos, int inlength, int[] out, IntWrapper outpos)
      Uncompress data from an array to another array. Both inpos and outpos parameters are modified to indicate new positions after read/write.
      Parameters:
      in - array containing data in compressed form
      inpos - where to start reading in the array
      inlength - length of the compressed data (ignored by some schemes)
      out - array where to write the compressed output
      outpos - where to write the compressed output in out
