template<typename T, ERefCountingMode Mode> class TRefCountingMixin

Remarks

Ref-counting mixin, designed to add ref-counting to an object without requiring a virtual destructor. Implements support for AutoRTFM, is thread-safe by default, and can support custom deleters via T::StaticDestroyObject.

AutoRTFM means that the return value of AddRef/Release is nonsense (as the ref-count doesn't change until the transaction is committed), but this is fine for use with TRefCountPtr (as it doesn't use those return values). Basic Example: struct FMyRefCountedObject : public TRefCountingMixin { // ... };

Deleter Example: struct FMyRefCountedPooledObject : public TRefCountingMixin { static void StaticDestroyObject(const FMyRefCountedPooledObject* Obj) { GPool->ReturnToPool(Obj); } };
