#include <functional>
#include <iostream>
class Plain {
public:
template <typename Type>
void member_function(const Type& s) {
std::cout << "Recived: " << s << std::endl;
}
};
template <typename Type>
class Templated : private Plain {
public:
};
int main() {
Plain b;
b.member_function<int>(10); // done!
Templated<int> d;
// d.member_function(); /* how to achive this */
return 0;
}
I am trying to call the member function in class Plain
by two method:
Plain p;
p.member_function<int>();
Templated<int> t;
t.member_function(); // achive this
I tried doing binding the function in derived class like
struct Plain{
template<typename T>
static void member_function(const T& s){std::cout << s << std::endl;}
}
template<typename T>
struct Templated : private Plain {
std::function<void(const T&)> print = Templated::Plain::member_function;
}
and after that I was able to do
Templated t<std::string>;
t.print();
I found a workaround
#include <functional>
#include <iostream>
using namespace std::placeholders;
struct Test {
template <typename Type>
void foo(const Type&) {
std::cout << "I am just a foo..." << std::endl;
return;
}
};
template <typename T>
struct Foo {
private:
Test* obj;
public:
Foo() : obj(new Test) {}
std::function<void(const int&)> foo = std::bind(&Test::foo<T>, obj, _1);
~Foo() { delete obj; }
};
int main() {
Foo<int> me;
me.foo(10);
Test t;
t.foo<int>(89);
std::cout << std::endl;
return 0;
}
