std::ranges::adjacent_view<V,N>::iterator

template< bool Const >
class /*iterator*/

(since C++23)
(exposition only*)

The return type of adjacent_view::begin, and of adjacent_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.

Member types

Member type	Definition
`Base` (private)	`const V` if `Const` is `true`, otherwise `V`. (exposition-only member type*)
`iterator_category`	`std::input_iterator_tag`
`iterator_concept`	`std::random_access_iterator_tag`, if `Base` models `random_access_range`. Otherwise, `std::bidirectional_iterator_tag`, if `Base` models `bidirectional_range`. Otherwise, `std::forward_iterator_tag`.
`value_type`	`std::tuple</REPEAT/(ranges::range_value_t<Base>, N)...>;`
`difference_type`	`ranges::range_difference_t<Base>`

Data members

Member object	Definition
`current_` (private)	`std::array<ranges::iterator_t<Base>, N>`. (exposition-only member object*)

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)
iter_move (C++23)	casts the result of dereferencing the underlying iterator to its associated rvalue reference type (function)
iter_swap (C++23)	swaps the objects pointed to by two underlying iterators (function)
