Member functions
std::ranges::repeat_view::iterator::iterator
| /*iterator*/() = default; |
(1) | (since C++23) |
constexpr explicit /*iterator*/ ( const W* value, /*index-type*/ b = /*index-type*/() ); |
(2) | (since C++23) (exposition only*) |
Constructs an iterator. Overload (2) is called by begin() and end() of ranges::repeat_view.
std::ranges::repeat_view::iterator::operator*
| constexpr const W& operator*() const noexcept; |
(since C++23) | |
Returns *value_.
std::ranges::repeat_view::iterator::operator[]
| constexpr const W& operator[]( difference_type n ) const noexcept; |
(since C++23) | |
Returns *(*this + n).
std::ranges::repeat_view::iterator::operator++
| constexpr /*iterator*/& operator++(); |
(1) | (since C++23) |
| constexpr void operator++(int); |
(2) | (since C++23) |
current_ ; return *this;.std::ranges::repeat_view::iterator::operator--
| constexpr /*iterator*/& operator--(); |
(1) | (since C++23) |
| constexpr /*iterator*/ operator--(int); |
(2) | (since C++23) |
current_ ; return *this;.Bound is not std::unreachable_sentinel_t and current_ is non-positive, the behavior is undefined.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 and current_ + n is negative, the behavior is undefined.
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 and current_ - n is negative, the behavior is undefined.
Non-member functions
operator==, <=>(std::ranges::repeat_view::iterator)
| friend constexpr bool operator== ( const /*iterator*/& x, const /*iterator*/& y ); |
(1) | (since C++23) |
| friend constexpr auto operator<=> ( const /*iterator*/& x, const /*iterator*/& y ); |
(2) | (since C++23) |
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 associated class of the arguments.
operator+(std::ranges::repeat_view::iterator)
| friend constexpr /*iterator*/ operator+ ( /*iterator*/ i, difference_type n ); |
(1) | (since C++23) |
| friend constexpr /*iterator*/ operator+ ( difference_type n, /*iterator*/ i ); |
(2) | (since C++23) |
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 associated class of the arguments.
operator-(std::ranges::repeat_view::iterator)
| friend constexpr /*iterator*/ operator- ( /*iterator*/ i, difference_type n ); |
(1) | (since C++23) |
| friend constexpr difference_type operator- ( const /*iterator*/& x, const /*iterator*/& y ); |
(2) | (since C++23) |
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 associated class of the arguments.
Notes
iterator is always random_access_iterator.
