Pass a template method as an argument

Question

Could some one help me how to implement this code?

I need to pass a function to another function:

std::cout << process_time(Model::method1) <<         


        

Answer 1

The key is that method1 is a function template:

template  double method1(std::vector& );

As such, it's not a function... it's a family of functions. process_time expects a single function, so you just have to pass it the one function that you want to use:

std::cout << process_time(method1) << std::endl;
