24. Sept. 2011 · The problem statement you make in the updated answer is already solved by 9.2p9 (see accepted answer's comment section). 9.2p9 forbids to put "override" on non-virtual functions. The only problem I see is the example, and it can be solved by just putting "virtual" before the function "f" in "D".
- What if B::f would not have been marked virtual? Is the program ill-formed, then? Yes, it is. Because in order to override something, that some...
- If B:f was non-virtual, then both D:f functions would be ill-formed.
- Yes, the program is ill formed when override is added to any non-virtual function. Generally, functions with differing signatures (overloaded), a...
The non-virtual interface pattern is a design pattern that controls how methods in a base class are overridden. Base classes include public, non-virtual members that may be called by clients and a set of overridable methods containing core functionality.

7. Mai 2019 · The NVI, or Non-Virtual Interface design pattern, is in a way a mechanism to extend the functionality of a function, just alike inheritance allow classes to be extended. It’s one way of implementing the strategy pattern.
24. Aug. 2022 · The Non-Virtual Interface is a way of implementation specific to C++. It decouples the public interface by making it non-virtual, from functions that are providing customization points.
3. Sept. 2022 · Non-Virtual Interface (NVI) idiom allows us to refactor before and after code fragments at one convenient location - the base class. The NVI idiom is based on 4 guidelines outlined by Herb Sutter in his article named "Virtuality" [2]. Quoting Herb: Guideline #1: Prefer to make interfaces nonvirtual, using Template Method design pattern.
A Simulink.Bus object data type must define the bus you want to make nonvirtual. A bus becomes nonvirtual when you select a block parameter such as Output as nonvirtual bus. Making the bus nonvirtual causes simulation and code generation to apply the structure defined by the bus object.
