std::ranges...w::iterator(3) C++ Standard Libary std::ranges...w::iterator(3) NAME std::ranges::repeat_view::iterator - std::ranges::repeat_view::iterator Synopsis struct /*iterator*/; (since C++23) (exposition only*) The return type of repeat_view::begin. Member types Member type Definition * std::ptrdiff_t, if Bound is the same as index-type std::unreachable_sentinel_t. Otherwise, * Bound. (exposition-only member type*) iterator_concept std::random_access_iterator_tag iterator_category std::random_access_iterator_tag value_type W * /*index-type*/, if /*is-signed-like*/</*index- type*/> is true, difference_type * /*iota-diff-t*/(/*index-type*/) otherwise, where /*iota-diff-t*/ has the same meaning as in iota_view. Data members Member name Definition A pointer of type const W* that holds the pointer to the value to value_ (private) repeat. (exposition-only member object*) current_ (private) An object of type /*index-type*/ that holds the cur- rent position. (exposition-only member object*) Member functions constructor constructs an iterator (C++23) (public member function) operator* returns the current subrange (C++23) (public member function) operator[] accesses an element by index (C++23) (public member function) operator++ operator++(int) operator-- advances or decrements the underlying iterator operator--(int) (public member function) operator+= operator-= (C++23) std::ranges::repeat_view::iterator::iterator /*iterator*/() = default; (1) (since C++23) constexpr explicit /*iterator*/( (2) (since C++23) const W* value, /*index-type*/ b = /*index-type*/() ); (exposi- tion only*) 1) Value initializes the data members: * value_ with nullptr_t via its default member initializer; * index_ via its default member initializer (= /*index-type*/()). 2) Value initializes value_ with value and bound_ with b. If Bound is not std::unreachable_sentinel_t then b must be non-negative. This construc- tor is not a part of the public interface. std::ranges::repeat_view::iterator::operator* constexpr const W& operator*() const noexcept; (since C++23) Equivalent to return *value_;. std::ranges::repeat_view::iterator::operator[] constexpr const W& operator[]( difference_type n ) const noexcept; (since C++23) Equivalent to return *(*this + n);. std::ranges::repeat_view::iterator::operator++ constexpr /*iterator*/& operator++(); (1) (since C++23) constexpr void operator++(int); (2) (since C++23) 1) Equivalent to ++current_; return *this;. 2) Equivalent to auto tmp = *this; ++*this; return tmp;. std::ranges::repeat_view::iterator::operator-- constexpr /*iterator*/& operator--(); (1) (since C++23) constexpr /*iterator*/ operator--(int); (2) (since C++23) 1) Equivalent to --current_; return *this;. If Bound is not std::unreachable_sentinel_t then bound_ must be positive. 2) Equivalent to auto tmp = *this; --*this; return tmp;. std::ranges::repeat_view::iterator::operator+= constexpr /*iterator*/& operator+=( difference_type n ); (since C++23) Equivalent to current_ += n; return *this;. If Bound is not std::unreachable_sentinel_t then (bound_ + n) must be non-negative. std::ranges::repeat_view::iterator::operator-= constexpr /*iterator*/& operator-=( difference_type n ); (since C++23) Equivalent to current_ -= n; return *this;. If Bound is not std::unreachable_sentinel_t, then (bound_ - n) must be non-negative. Non-member functions operator== compares the underlying iterators operator<=> (function) (C++23) operator+ performs iterator arithmetic operator- (function) (C++23) operator==, <=>(std::ranges::repeat_view::iterator) friend constexpr bool operator==( const /*iterator*/& x, const (1) (since C++23) /*iterator*/& y ); friend constexpr auto operator<=>( const /*iterator*/& x, const (2) (since C++23) /*iterator*/& y ); 1) Equivalent to x.current_ == y.current_. 2) Equivalent to x.current_ <=> y.current_. The != operator is synthesized from operator==. These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when iterator is an associ- ated class of the arguments. operator+(std::ranges::repeat_view::iterator) friend constexpr /*iterator*/ operator+( /*iterator*/ i, (1) (since C++23) difference_type n ); friend constexpr /*iterator*/ operator+( difference_type n, (2) (since C++23) /*iterator*/ i ); Equivalent to i += n; return i;. These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when iterator is an associ- ated class of the arguments. operator-(std::ranges::repeat_view::iterator) friend constexpr /*iterator*/ operator-( /*iterator*/ i, (1) (since C++23) difference_type n ); friend constexpr difference_type operator-( const /*iterator*/& x, const /*iterator*/& y (2) (since C++23) ); 1) Equivalent to i -= n; return i;. 2) Equivalent to return static_cast<difference_type>(x.current_) - static_cast<difference_type>(y.current_);. These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when iterator is an associ- ated class of the arguments. Notes iterator is always random_access_iterator. http://cppreference.com 2024.06.10 std::ranges...w::iterator(3)
