Yes, but why Do you need to? There are two common responses: for performance: to prevent my purpose calls becoming Digital for safety: in order that my course is not made use of to be a foundation class (for example, to make sure that I am able to copy objects without the need of fear of slicing) In my knowledge, the efficiency reason is normally misplaced concern. In C++, Digital purpose phone calls are so quick that their real-environment use for a category designed with virtual features would not to produce measurable run-time overheads when compared with alternate solutions making use of regular function calls. Be aware that the virtual purpose connect with mechanism is usually utilised only when contacting via a pointer or possibly a reference. When calling a operate straight for any named object, the Digital operate class overhead is definitely optimized absent. When there is a real need for "capping" a class hierarchy to prevent Digital function calls, one may possibly request why Those people functions are Digital to begin with.
