An atomic operation usually has very little in frequent with transactions. To my know-how this emanates from hardware programming, wherever an set of functions (or 1) transpire to receive solved promptly.
– tc. Commented Dec 1, 2010 at eighteen:20 @fyolnish I am not sure what _val/val are, but no, probably not. The getter for an atomic duplicate/keep property requires making sure that it doesn't return an object whose refcount gets to be zero owing the setter being referred to as in A different thread, which fundamentally usually means it must study the ivar, keep it though guaranteeing that the setter has not overwritten-and-produced it, then autorelease it to balance the keep.
