A store operation using this memory get performs the discharge Procedure: no reads or writes in the current thread might be reordered just after this store. All writes in The present thread are obvious in other threads that purchase the identical atomic variable
Dealing with While using the shared useful resource will become necessary wherever many threads entry and modify shared sources. In this kind of circumstance, among the options may be an atomic variable. And there's no need to have of explicit synchronization utilizing synchronized or risky key word.
When an atomic load is executed on a shared variable, it reads your complete price as it appeared at just one instant in time."
I failed to need to pollute global namespace with 'id', so I place it as a static while in the function; on the other hand in that case you will need to Be sure that on your own platform that doesn't bring on actual initialization code.

Commented Dec ten, 2013 at 11:09 @tc It's been quite some time but what I intended to write down Atomic Wallet was most likely this: gist.github.com/fjolnir/5d96b3272c6255f6baae But Of course it is feasible with the previous benefit for being browse by a reader ahead of setFoo: returns, and released prior to the reader returns it. But it's possible In the event the setter made use of -autorelease as an alternative to -launch, that will deal with that.
