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

< cpp‎ | ranges‎ | join view

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

The return type of join_view::begin, and of join_view::end when the underlying view 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.

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)
