Web a member function template cannot be virtual, and a member function template in a derived class cannot override a virtual member function from the base class. Web a function template defines a family of functions. You cannot have virtual template functions (which is essentially what you have since it takes a templated type as a parameter, even though the template is on the class, not the function). Why would we need a virtual template function? And we'll do it all with one single vtable! Unfortunately, you can’t do that. Web templated virtual member functions are not supported in c++ but i have a scenario where it would be ideal. Web in part 1 of this series we learned how to implement a virtual function template with a variadic parameter pack. Web feb 4, 2009 at 4:52am. Void run(.) switch(some_int_value_from_the_input) { case 1: Static data member of a class template.

Virtual Template Function

As templates are resolved at compile time, virtual will not work, as the compiler would not know which template to pick. Variable template (since c++14) member function of a class.

Template Virtual Function

Now i've packed all those things up in a few classes to make it prettier or more confortable to use and extend. In this post we're going to expand on.
