24 de set. de 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".
The non-virtual interface pattern (NVI) controls how methods in a base class are overridden. Such methods may be called by clients and overridable methods with core functionality. It is a pattern that is strongly related to the template method pattern.

After having read the title, you might ask why we speak both about The Template Method Pattern (TMP from now on) and Non-Virtual Idiom (NVI from now on). The TMP is a classic design pattern from the Gang Of Four book and NVIis an idiom specific to C++. TMPis the go-to pattern when you have to implement an algorithm with a given structure but where ...
It’s time to discuss the Non-Virtual Interfaceidiom. You might have noticed that the virtual functions we created are listed after a private access specifier. Software development is about breaking down complexities. Programming is about making the complex simple. Just think about the first SOLIDprinciple. An entity should be responsible for one th...
The Template Method Pattern can be used with any object-oriented language and despite its name, it has nothing to do with generics. 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. It’s all about making complex th...

Deciding what works and what doesn’t work for you early is vital in leveraging value gained from going virtual, non-virtual, or a combination of the two. It’s safe to say that many businesses will continue with virtual events and meetings in some circumstance – some much more often than pre-pandemic.
Using the Turtle interface as example, here are the simple steps you need to follow: Derive a class MockTurtle from Turtle. Take a virtual function of Turtle (while it’s possible to mock non-virtual methods using templates , it’s much more involved). In the public: section of the child class, write MOCK_METHOD();
