add_reference Class
Makes reference to type from type.
template<class Ty>
struct add_reference;
Parameters
- Ty
The type to modify.
Remarks
An instance of the type modifier holds a modified-type that is Ty if Ty is a reference, otherwise Ty&.
Example
// std_tr1__type_traits__add_reference.cpp
// compile with: /EHsc
#include <type_traits>
#include <iostream>
int main()
{
int val = 0;
std::add_reference<int>::type p = (int&)val;
p = p; // to quiet "unused" warning
std::cout << "add_reference<int> == "
<< typeid(p).name() << std::endl;
return (0);
}
add_reference<int> == int
