std::experimental::ranges::projected(3)

NAME
std::experimental::ranges::projected - std::experimental::ranges::projected

Synopsis
Defined in header <experimental/ranges/iterator> template< Readable I, IndirectRegularUnaryInvocable<I> Proj > struct projected {
    using value_type = std::remove_cv_t<std::remove_reference_t<ranges::indirect_result_of_t<Proj&(I)>>>;
    ranges::indirect_result_of_t<Proj&(I)> operator*() const; (ranges }; TS) template< WeaklyIncrementable I, class Proj > struct difference_type<projected<I, Proj>> {
    using type = ranges::difference_type_t<I>; };
   The class template projected bundles a Readable type I and a function Proj into a
   new Readable type whose reference type is the result of applying Proj to the
   reference type of I. It exists solely to ease constraint specification, and so its
   operator*() may not be actually defined.
