5, 10) Le F type doit être CopyConstructible et le f objet doit être Callable. L'objet fonction qui en résulte qui est créé sera vide si f est un pointeur de fonction NULL, un pointeur NULL à un membre, ou si f est un std::function et !f == true. Le f argument est déplacé en fonction de l'objet en découlent .

Original:

5, 10) The type F should be CopyConstructible and the object f should be Callable. The resulting function object that is created will be empty if f is a NULL function pointer, a NULL pointer to member, or if f is a std::function and !f == true. The argument f is moved into the resulting function object.
