| Creates a new value, initialised to zero. | |
| Atomic (Type initialValue) noexcept | |
| Creates a new value, with a given initial value. | |
| Atomic (const Atomic &other) noexcept | |

noexcept |
Atomically compares this value with a target value, and if it is equal, sets this to be equal to a new value.
This operation is the atomic equivalent of doing this:
Internally, this method calls std::atomic::compare_exchange_strong with memory_order_seq_cst (the strictest std::memory_order).
