std::ranges::join_view<V>::iterator

template< bool Const >
class /*iterator*/

(since C++20)
(exposition only*)

The return type of join_view::begin, and of join_view::end when both the outer range V and the inner range ranges::range_reference_t<V> satisfy common_range and the parent join_view is a forward_range.

If V is not a simple view (e.g. if ranges::iterator_t<constV> is invalid or different from ranges::iterator_t<V>), Const is true for iterators returned from the const overloads, and false otherwise. If V is a simple view, Const is true if and only if ranges::range_reference_t<V> is a reference.

Member types

Member	Definition
`Parent`	`maybe-const` <Const,ranges::join_view<V>> (exposition-only member type*)
`Base`	`maybe-const` <Const,V> (exposition-only member type*)
`OuterIter`	ranges::iterator_t<Base> (exposition-only member type*)
`InnerIter`	ranges::iterator_t<ranges::range_reference_t<Base>> (exposition-only member type*)
`iterator_concept`	`std::bidirectional_iterator_tag`, if ranges::range_reference_t<Base> is a reference type, and `Base` and ranges::range_reference_t<Base> each model `bidirectional_range`; `std::forward_iterator_tag`, if ranges::range_reference_t<Base> is a reference type, and `Base` and ranges::range_reference_t<Base> each model `forward_range`; `std::input_iterator_tag` otherwise.
`iterator_category` (conditionally present)	Defined only if `iterator::iterator_concept` (see above) denotes `std::forward_iterator_tag`. Let `OUTERC` be std::iterator_traits<ranges::iterator_t<Base>>::iterator_category, and let `INNERC` be `std::iterator_traits<ranges::iterator_t<ranges::range_reference_t<Base>>>::iterator_category`. `std::bidirectional_iterator_tag`, if `OUTERC` and `INNERC` each model std::derived_from<std::bidirectional_iterator_tag>; `std::forward_iterator_tag`, if `OUTERC` and `INNERC` each model std::derived_from<std::forward_iterator_tag>; `std::input_iterator_tag` otherwise.
`value_type`	ranges::range_value_t<ranges::range_reference_t<Base>>
`difference_type`	`std::common_type_t<ranges::range_difference_t<Base>,ranges::range_difference_t<ranges::range_reference_t<Base>>>`

Data members

Member	Definition
`OuterIter` `outer_` (private)	An outer iterator (exposition-only member object*)
`InnerIter` `inner_` (private)	An inner iterator (exposition-only member object*)
`Parent*` `parent_` (private)	A pointer to the parent object (exposition-only member object*)

Member functions

(constructor)	constructs an iterator (public member function)
operator*operator->	accesses the element (public member function)
operator++operator++(int)operator--operator--(int)	advances or decrements the underlying iterators (public member function)
satisfy	skips over empty inner ranges (exposition-only member function*)

Non-member functions

operator== (C++20)	compares the underlying iterators (function)
iter_move (C++20)	casts the result of dereferencing the underlying iterator to its associated rvalue reference type (function)
iter_swap (C++20)	swaps the objects pointed to by two underlying iterators (function)
