How to restrict overiding a function in derived class?

[Pankh]

Hi,

Is it possible to restrict overiding a function in derived class?
To be more clear, I have base class with function foo() and I do not
want any derived class to implement foo() again. Always base version
of foo() should be called on any derived class object. Can I do that?

Thanks.

No, sorry. You have to write it into your documentation, that this
method must not be overridden.

Kind regards,

From your specific description, just make foo non-virtual.
