template< bool Const > class /*iterator*/		(since C++20)

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<const V> 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.

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

Member types

Member type	Definition
Parent (private)	const join_view<V> if Const is true, otherwise join_view<V>. The name is for exposition only.
Base (private)	const V if Const is true, otherwise V. The name is for exposition only.
OuterIter (private)	ranges::iterator_t<Base>. The name is for exposition only.
InnerIter (private)	ranges::iterator_t<ranges::range_reference_t<Base>>. The name is for exposition only.
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	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>>>

Member objects

Member name	Definition
outer_ (private)	an object of type OuterIter. The name is for exposition only.
inner_ (private)	an object of type InnerIter. The name is for exposition only.
parent_ (private)	an object of type Parent. The name is for exposition only.

Member functions

(constructor) (C++20)	constructs an iterator (public member function)
operator*operator-> (C++20)	accesses the element (public member function)
operator++operator++(int)operator--operator--(int) (C++20)	advances or decrements the underlying iterators (public member function)
satisfy (C++20)	skips over empty inner ranges; the name is for exposition only (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)
