Templates, Delegates, Blueprints: how would I do this?

Development Programming & Scripting

The end goal I want is to have some function essentially works like:

UFUNCTION(BlueprintCallable)
template<typename T>
AddTrackedData(UObject* objRef, [delegate T()] getterFunc, [delegate void(T)] setterFunc);

where [delegate T()] is a delegate which returns T and [delegate void(T)] is a delegate which takes a parameter T.

This is relatively straight-forward to do as a templated function, however, the UFUNCTION and other macros don’t seem to play nice with templates.

The function is used in order to create a new instance of DataTracker

template<typename T>
class DataTracker {
  TWeakPtr<UObject> objRef;
  T data;
};

Only instead of directly storing the data, I want to indirectly reference it using a getter and setter function like so

template<typename T>
class DataTracker {
public:
  TWeakPtr<UObject> objRef;
  DECLARE_DELEGATE_RetVal(T, FGetDelegate)
  DECLARE_DELEGATE_OneParam(FSetDelegate, T)
  FGetDelegate getValueFunction;
  FSetDelegate setValueFunction;
};

If at all possible, I’d like to be able to set tracked data in blueprints, but I haven’t been able to figure out a way to go about that.
