    • u4At

      public int u4At(int relativeOffset)
      Returns an 32 bit integer created of 4 bytes. The return value should be treated as an unsigned integer! i.e. if the caller does math with the result he should use the unsigned methods from Integer like Integer.toUnsignedLong(int) or Integer.compareUnsigned(int, int). Note that addition with the + operator is safe to use.
      Parameters:
      relativeOffset - unsigned integer
      Returns:
      unsigned integer
