TMulticastDelegateRegistration< DelegateSignature, UserPolicy > Class Template Reference

Detailed Description

template<typename DelegateSignature, typename UserPolicy = FDefaultDelegateUserPolicy>
class TMulticastDelegateRegistration< DelegateSignature, UserPolicy >

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<void()>& OnInterestingThing() const { return OnInterestingThingDelegate; }

private: mutable TMulticastDelegate<void()> 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 }
