Don't you think that operator overloading is a better and more elegant
solution ?
#include <iostream>
#include <sstream>
#include <vector>
#include <string>
using namespace std;
class Foo {
private:
int x;
int y;
public:
Foo(int xv, int yv)
: x(xv)
, y(yv) {};
friend ostream& operator<< (ostream& os, const Foo& f);
};
ostream& operator<< (ostream& os, const Foo& f) {
os << "(" << &f << ") = Foo(" << f.x << ", " << f.y << ")";
}
template <typename T>
string toString(const T& val) {
ostringstream os;
os << val;
return os.str();
}
int main() {
Foo f(1,2);
cout << toString(f) << endl;
}
