...one of the most highly
regarded and expertly designed C++ library projects in the
world.
— Herb Sutter and Andrei
Alexandrescu, C++
Coding Standards
template <class T>
struct add_lvalue_reference
{
typedef see-below
type;
};
type: If T
names an object or function type then the member typedef type
shall name T&
;
otherwise, if T
names a type
rvalue reference to U then the member typedef type shall
name U&
;
otherwise, type shall name T
.
C++ Standard Reference: 20.7.6.2.
Compiler Compatibility: If the compiler
does not support partial specialization of class-templates then this template
will compile, but the member type
will always be the same as type T
except where compiler
workarounds have been applied.
