std::experimental::ranges::DerivedFrom(3) | C++ Standard Libary | std::experimental::ranges::DerivedFrom(3) |
NAME¶
std::experimental::ranges::DerivedFrom - std::experimental::ranges::DerivedFrom
Synopsis¶
Defined in header <experimental/ranges/concepts>
template< class T, class U >
concept bool DerivedFrom =
std::is_base_of<U, T>::value && (ranges TS)
std::is_convertible<std::remove_cv_t<T>*,
std::remove_cv_t<U>*>::value;
The concept DerivedFrom<T, U> is satisfied if and only if U is a class
type that is
either T or a public and unambiguous base of T.
Despite the use of std::is_base_of and std::is_convertible in its description
above,
DerivedFrom is not required to use it in its implementation. Thus, there need
not be
any subsumption relationship between DerivedFrom<T, U> and
std::is_base_of<U,T>::value or
std::is_convertible<std::remove_cv_t<T>*,
std::remove_cv_t<U>*>::value.
