Yep that's what I do not recognize. What is meant by earning an object atomic. If there was an interface it could simply are actually manufactured atomic using a mutex or a watch.
atomicity of a single assets also are unable to promise thread security when multiple dependent Houses are in Engage in.
That effectively suggests the two the getter and setter really have to make use of a lock (if the memory format was fixed it ought Atomic Wallet to be doable with CAS2 instructions; alas -retain is a technique get in touch with).
What Aim-C does, is ready a lock, so only the actual thread might entry the variable, given that the setter/getter is executed. Example with MRC of a home by having an ivar _internal:

The majority of the atom is vacant Place. The rest includes a few primary forms of subatomic particles: protons, neutrons, and electrons. The protons and neutrons kind the atom’s central nucleus. (The normal hydrogen atom is definitely an exception; it contains just one proton but no neutrons.) As their names propose, protons Possess a positive electrical cost, although neutrons are electrically neutral—they have no cost; overall, then, the nucleus provides a constructive charge.
