  • Method Details

    • fillBytesWithZeroes

      static void fillBytesWithZeroes(byte[] dest, int start, int end)
      Fills byte array with zeroes.

      Current implementation uses System.arraycopy(Object, int, Object, int, int), so it should be used for length not less than 16.

      Parameters:
      dest - array to fill with zeroes
      start - the first item to fill
      end - the last item to fill (exclusive)

    • fillIntsWithZeroes

      static void fillIntsWithZeroes(int[] dest, int start, int end)
      Fills int array with zeroes.

      Current implementation uses System.arraycopy(Object, int, Object, int, int), so it should be used for length not less than 16.

      Parameters:
      dest - array to fill with zeroes
      start - the first item to fill
      end - the last item to fill (exclusive)

    • copyBytes

      static void copyBytes(byte[] dst, int target, byte[] src, int start, int end)

    • copyBytesWithin

      static void copyBytesWithin(byte[] bytes, int target, int start, int end)

    • readInput
