Is there a way to use a reference as a member variable without initialising it in the constructor?
My problem is that I don’t have the reference at hand when constructing the object.

In that case you have to go for a pointer and initialize it to NULL. Then later when you have the object make the pointer point to that. A reference cannot be used in this case as you cannot initialize reference to NULL
