Detailed Description

An alternative to bool for additional thread safety.

The class Boolean provides an alternative to bool. std::vector<bool> is not thread safe due to the possibility of multiple bits being packed together in the same memory location. std::vector<Boolean> does not have such a space optimization. std::vector<Boolean> is semantically like std::vector<bool>, but unlike std::vector<bool>, it does "avoid data races when the contents of the contained object in different elements in the same container [...] are modified concurrently", according to the C++ Standard, section [container.requirements.dataraces], "Container data races".
