    • fillBytesWithZeroes

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

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

      Parameters:
      dest - array to fill with zeroes
      offset - the first byte to fill
      length - number of bytes to change

    • fillIntsWithZeroes

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

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

      Parameters:
      dest - array to fill with zeroes
      offset - the first item to fill
      length - number of item to change

    • 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

      static int readInput(InputStream src, byte[] dst, int offset, int length)

    • closeInput

      static void closeInput(InputStream src) throws IOException
      Throws:
      IOException
