Certainly, but why do you want to? There are 2 frequent responses: for performance: to stay away from my purpose calls remaining virtual for security: to make sure that my course is not made use of like a foundation class (one example is, to be sure that I can copy objects without having panic of slicing) In my encounter, the performance rationale is frequently misplaced fear. In C++, Digital function phone calls are so speedy that their real-world use for a category designed with Digital features won't to generate measurable operate-time overheads compared to alternative answers making use of normal operate calls. Notice that the virtual operate get in touch with mechanism is often utilised only when calling by way of a pointer or maybe a reference. When calling a function specifically for the named object, the virtual perform course overhead is definitely optimized absent. If there is a genuine have to have for "capping" a category hierarchy to stay away from virtual operate calls, a single may inquire why Individuals capabilities are virtual to start with.
