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

The iterator type of a possibly const-qualified zip_transform_view, returned by zip_transform_view::begin and in certain cases by zip_transform_view::end. The name of this class template (shown here as iterator) is unspecified.

The type /*iterator*/<true> or /*iterator*/<false> treats the underlying views as const-qualified or non-const-qualified respectively.

Member types

Member type	Definition
Parent (private)	zip_transform_view if Const is false, const zip_transform_view otherwise. The name is for exposition only.
Base (private)	InnerView if Const is false, const InnerView otherwise. The name is for exposition only.
iterator_category	Let /*maybe-const*/<Const, F>& denote const F& if Const is true, F& otherwise. Let /*maybe-const*/<Const, Views> denote const Views if Const is true, Views otherwise. Let /*POT*/ denote the pack of types std::iterator_traits<std::iterator_t<     /*maybe-const*/<Const, Views>>>::iterator_category... If /*Base*/ models forward_range, then iterator_category denotes: std::input_iterator_tag, if std::invoke_result_t</*maybe-const*/<Const, F>&,     ranges::range_reference_t</*maybe-const*/<Const, Views>>...> is not a reference. Otherwise, std::random_access_iterator_tag, if (std::derived_from</*POT*/, std::random_access_iterator_tag> && ...) is true. Otherwise, std::bidirectional_iterator_tag, if (std::derived_from</*POT*/, std::bidirectional_iterator_tag> && ...) is true. Otherwise, std::forward_iterator_tag, if (std::derived_from</*POT*/, std::forward_iterator_tag> && ...) is true. Otherwise, std::input_iterator_tag. Not present if /*Base*/ does not model forward_range.
iterator_concept	/*ziperator*/<Const>::iterator_concept
value_type	Let /*RREF*/ be ranges::range_reference_t<Views>..., and /*CRREF*/ be ranges::range_reference_t<const Views>.... Then: std::remove_cvref_t<std::invoke_result_t<F&, /*RREF*/>> if Const is false, std::remove_cvref_t<std::invoke_result_t<const F&, /*CRREF*/>> otherwise.
difference_type	range::range_difference_t</*Base*/>

Data members

Typical implementations of iterator hold two non-static data members:

• a pointer parent_ of type Parent to the parent object
• an iterator inner_ of type ziperator<Const>.

These names are for exposition purposes only.

Member functions

(constructor) (C++23)	constructs an iterator (public member function)
operator* (C++23)	obtains the result of applying the invocable object to the underlying poined-to elements (public member function)
operator[] (C++23)	obtains the result of applying the invocable object to the underlying elements at given offset (public member function)
operator++operator++(int)operator--operator--(int)operator+=operator-= (C++23)	advances or decrements the underlying iterator (public member function)

Non-member functions

operator==operator<=> (C++23)	compares the underlying iterators (function)
operator+operator- (C++23)	performs iterator arithmetic on underlying iterators (function)
