The flags discussed so far are unordered as well. E.g. OpenMode.RDONLY |
OpenMode.WRONLY | OpenMode.CLOEXEC == OpenMode.RDONLY | OpenMode.CLOEXEC |
OpenMode.WRONLY or any other permutation. In other words, flags (aka
bitmasks) are just an optimized representation of an (unordered) set of
small integer values.
