Type Traits that Transform One Type to Another

The following templates transform one type to another, based upon some well-defined rule. Each template has a single member called type that is the result of applying the transformation to the template argument T.

Synopsis:

template <class T>
struct add_const;

template <class T>
struct add_cv;

template <class T>
struct add_lvalue_reference;

template <class T>
struct add_pointer;

template <class T>
struct add_reference;

template <class T>
struct add_rvalue_reference;

template <class T>
struct add_volatile;

template <bool B, class T, class U>
struct conditional;

template <class... T>
struct common_type;

template <class T, class U>
struct copy_cv;

template <class T>
struct decay;

template <class T>
struct floating_point_promotion;

template <class T>
struct integral_promotion;

template <class T>
struct make_signed;

template <class T>
struct make_unsigned;

template <class T>
struct promote;

template <class T>
struct remove_all_extents;

template <class T>
struct remove_const;

template <class T>
struct remove_cv;

template <class T>
struct remove_extent;

template <class T>
struct remove_pointer;

template <class T>
struct remove_reference;

template <class T>
struct remove_volatile;

template <class T>
struct type_identity;
