Multicast delegate registration class. A function can expose this base class to users to let them bind against, but without letting them broadcast. This gives us the benefit of C# events.

Example:

struct FInterestingThing { public: TMulticastDelegateRegistration& OnInterestingThing() const { return OnInterestingThingDelegate; }

private: mutable TMulticastDelegate OnInterestingThingDelegate; };

void Func(const FInterestingThing& Thing) { // Registration and reregistration are allowed FDelegateHandle Handle = Thing.OnInterestingThing().Add([](){ RespondToInterestingThing(); }); Thing.OnInterestingThing().Remove(Handle);

// Broadcast is not Thing.OnInterestingThing().Broadcast(); // error: Broadcast is deleted }
