template< bool Const > class /*iterator*/		(since C++23) (exposition only*)

The return type of cartesian_product_view::begin, and of cartesian_product_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	Definition
Parent (private)	maybe-const <Const, ranges::cartesian_product_view>> (exposition-only member type*)
iterator_category	std::input_iterator_tag
iterator_concept	std::random_access_iterator_tag, if /*cartesian-product-is-random-access*/<Const, First, Vs...> is modeled, std::bidirectional_iterator_tag, if /*cartesian-product-is-bidirectional*/<Const, First, Vs...> is modeled, std::forward_iterator_tag, if maybe-const <Const, First> models forward_range, std::input_iterator_tag, otherwise.
value_type	std::tuple<ranges::range_value_t</*maybe-const*/<Const, First>>,            ranges::range_value_t</*maybe-const*/<Const, Vs>>...>;
reference	std::tuple<ranges::range_reference_t</*maybe-const*/<Const, First>>,            ranges::range_reference_t</*maybe-const*/<Const, Vs>>...>;
difference_type	An implementation-defined signed-integer-like type (maybe the smallest of such types), which is sufficiently wide to store the product of the maximum sizes of all underlying ranges, if such type exists.

Data members

Member	Definition
Parent* parent_ (private)	A pointer to the parent object cartesian_product_view (exposition-only member object*)
current_ (private)	A tuple of iterators to the current underlying elements of type std::tuple<ranges::iterator_t</*maybe-const*/<Const, First>>,            ranges::iterator_t</*maybe-const*/<Const, Vs>>...> (exposition-only member object*)

Member functions

(constructor)	constructs an iterator (public member function)
operator*	accesses the element (public member function)
operator[]	accesses an element by index (public member function)
operator++operator++(int)operator--operator--(int)operator+=operator-=	advances or decrements the underlying iterator (public member function)
next	advances the iterator (exposition-only member function*)
prev	decrements the iterator (exposition-only member function*)
distance_from	returns the distance between two iterators (exposition-only member function*)

Non-member functions

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 underlying pointed-to elements (function)
