What "atomic" will not do is make any ensures about thread protection. If thread A is calling the getter concurrently with thread B and C contacting the setter with different values, thread A could get any on the list of three values returned -- the a single previous to any setters being referred to as or both of your values passed in to the setters in B and C.
