NAME¶

std::experimental::ranges::DerivedFrom - std::experimental::ranges::DerivedFrom

Synopsis¶

Defined in header <experimental/ranges/concepts>
template < class T, class U >

concept bool DerivedFrom = (ranges TS)
std::is_base_of<U, T>::value &&

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.
