std::ranges::adjacent_transform_view<V,F,N>::iterator

template< bool Const >
class /*iterator*/

(since C++23)

The return type of adjacent_transform_view::begin, and of adjacent_transform_view::end when the underlying view V is a common_range.

The type /*iterator*/<true> is returned by the const-qualified overloads. The type /*iterator*/<false> is returned by the non-const-qualified overloads.

The name of this class template (shown here as /*iterator*/) is unspecified.

Data members

Typical implementations of /*iterator*/ hold two non-static data members:

parent_ of type Parent*, and
inner_ of type inner_iterator.

These names are for exposition only.

Member types

Member type	Definition
`Parent` (private)	`const ranges::adjacent_transform_view`, if `Const` is `true`. Otherwise, `ranges::adjacent_transform_view`. The name is for exposition only.
`Base` (private)	`const V`, if `Const` is `true`. Otherwise, `V`. The name is for exposition only.
`iterator_category`	`std::input_iterator_tag`, if `std::invoke_result_t</maybe-const/<Const, F>&, /REPEAT/(ranges::range_reference_t<Base>, N)...>` is not a reference. Otherwise, let `C` denote the type `std::iterator_traits<iterator_t<Base>>::iterator_category`. `std::random_access_iterator_tag`, if `std::derived_from<C, std::random_access_iterator_tag>` is `true`. Otherwise, `std::bidirectional_iterator_tag`, if `std::derived_from<C, std::bidirectional_iterator_tag>` is `true`. Otherwise, `std::forward_iterator_tag`, if `std::derived_from<C, std::forward_iterator_tag>` is `true`. Otherwise, `std::input_iterator_tag`.
`iterator_concept`	`typename /inner-iterator/<Const>::iterator_concept;`.
`value_type`	`std::remove_cvref_t<std::invoke_result_t</maybe-const/<Const, F>&, /REPEAT/(ranges::range_reference_t<Base>, N)...>>;`
`difference_type`	`ranges::range_difference_t<Base>`

Member functions

(constructor) (C++23)	constructs an iterator (public member function)
operator* (C++23)	accesses the element (public member function)
operator[] (C++23)	accesses an element by index (public member function)
operator++operator++(int)operator--operator--(int)operator+=operator-= (C++23)	advances or decrements the underlying iterators (public member function)

Non-member functions

operator==operator<operator>operator<=operator>=operator<=> (C++23)	compares the underlying iterators (function)
operator+operator- (C++23)	performs iterator arithmetic (function)
