Virtual Template Function C
Virtual Template Function C - You will never be able to call fun() as a virtual method. You cannot have virtual template functions (which is essentially what you have since it takes a templated type as a. Virtual functions in c++ allow derived classes to override base class methods, enabling runtime polymorphism through late binding, while adhering to specific rules and. One example in c++ of wanting a virtual function template is a member function that accepts a generic iterator. It allows you to define a virtual function within a template class, enabling polymorphic behavior while. Template // t is a placeholder type returntype functionname(t parameter) { // function body } where: In this post we're going to expand on our code to allow for an.
As templates are resolved at compile time, virtual will not work, as the compiler would not know which template to pick. First, you cannot have virtual template functions. In this post we’re going to expand on our code to allow for an. A class template can indeed contain virtual or pure virtual functions.
One example in c++ of wanting a virtual function template is a member function that accepts a generic iterator.

You will never be able to call fun() as a virtual method. You cannot have virtual template functions (which is essentially what you have since it takes a templated type as a. Since virtual template methods in c++ arent allowed, you can make a class template and call static function of class template param. The documentation for boost.typeerasure includes an example polymorphic range formatter which simulates the concept of a pure virtual template member function.
