Yes, but why do you want to? There's two popular solutions: for effectiveness: to stop my function calls becoming Digital for security: to make certain that my course will not be applied for a foundation class (as an example, to make certain that I'm able to duplicate objects with no worry of slicing) In my working experience, the efficiency motive is normally misplaced dread. In C++, Digital perform calls are so speedy that their genuine-planet use for a class designed with virtual functions would not to generate measurable operate-time overheads when compared to option solutions utilizing everyday function phone calls. Note the virtual functionality simply call system is usually utilised only when calling through a pointer or simply a reference. When contacting a perform directly for your named object, the Digital operate class overhead is definitely optimized absent. When there is a real need to have for "capping" a category hierarchy to prevent virtual operate phone calls, just one might request why These capabilities are virtual in the first place.
