Syntax

template<typename T>
class TAtomic : public UE4Atomic_Private::TAtomicBaseType_T< T >

Remarks

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)
