Syntax
template<typename T>
class TAtomic : public UE::Core::Private::Atomic::TAtomicBaseType_T< T >
Remarks
DEPRECATED! UE atomics are not maintained and potentially will be physically deprecated. Use std::atomic
Atomic object wrapper class which wraps an element of T. This allows the following benefits:
- Changes made to the element on one thread can never be observed as a partial state by other threads. (atomicity)
- Memory accesses within a thread are not reordered across any access of the element. (acquire/release semantics)
- There is a single, visible, global order of atomic accesses throughout the system. (sequential consistency)
