WebObjects of atomic types contain a value of a particular type (T).The main characteristic of atomic objects is that access to this contained value from different threads cannot cause data races (i.e., doing that is well-defined behavior, with accesses properly sequenced).Generally, for all other objects, the possibility of causing a data race for …
