std::ranges::transform_view<V,F>::iterator - cppreference.com (original) (raw)

| template< bool Const > class /*iterator*/ | | (since C++20) (exposition only*) | | -------------------------------------------- | | --------------------------------- |

The return type of transform_view::begin, and of transform_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.

[edit] Member types

Member type	Definition
Parent (private)	maybe-const <Const, ranges::transform_view<V, F>>(exposition-only member type*)
Base (private)	maybe-const <Const, V>(exposition-only member type*)
iterator_concept	std::random_access_iterator_tag, if Base models random_access_range,std::bidirectional_iterator_tag, if Base models bidirectional_range,std::forward_iterator_tag, if Base models forward_range,std::input_iterator_tag otherwise.
iterator_category(present only if Base modelsforward_range)	Let MCF be maybe-const <Const, F>.std::input_iterator_tag, if std::invoke_result_t<MCF&, ranges::range_reference_t<Base>> is not a reference. Otherwise, let C be std::iterator_traits<ranges::iterator_t<Base>>::iterator_category. std::random_access_iterator_tag, if C is std::contiguous_iterator_tag; C, otherwise.
value_type	std::remove_cvref_t<std::invoke_result_t<MCF&, ranges::range_reference_t<Base>>>, where MCF denotes maybe-const <Const, F>
difference_type	ranges::range_difference_t<Base>

[edit] Data members

Member name	Definition
current_ (private)	An iterator into (possibly const-qualified) V.(exposition-only member object*)
parent_ (private)	A pointer to parent transform_view.(exposition-only member object*)
