std::ranges::transform_view<V,F>::iterator<Const>::iterator

From cppreference.com
 
 
 
 
/*iterator*/() = default;
(1) (since C++20)
constexpr /*iterator*/( Parent& parent, ranges::iterator_t<Base> current );
(2) (since C++20)
constexpr /*iterator*/( /*iterator*/<!Const> i )

  requires Const &&

           std::convertible_to<ranges::iterator_t<V>, ranges::iterator_t<Base>>;
(3) (since C++20)

Construct an iterator.

1) Default constructor. Value-initializes the underlying iterator, and initializes the pointer to parent transform_view with nullptr.
2) Intializes the underlying iterator with std::move(current), and the pointer to parent with std::addressof(parent).
3) Conversion from /*iterator*/<false> to /*iterator*/<true>. Move constructs corresponding members.

[edit] Parameters

parent - a (possibly const-qualified) transform_view
current - an iterator into (possibly const-qualified) V
i - an /*iterator*/<false>
