We usually use the onSuchAndSuch() naming style for this pattern:

public:
   /* non-virtual */ void suchAndSuch() {
        // some common code here to assert, canonicalize inputs, early out, etc
here
        this->onSuchAndSuch();
   }

private:
   virtual void onSuchAndSuch() { // do the real subclass-specific meaty work
here }



Maybe we should call this just resourceSizeDidChange() or
sendResourceSizeChangeNotification() or something like that.

Done.
