成员函数

iota_view::sentinel::sentinel

非成员函数

operator==(iota_view::iterator,iota_view::sentinel)

operator-(iota_view::iterator,iota_view::sentinel)

 

struct /*sentinel*/;		(仅作说明*)

ranges::iota_view<W, Bound>::sentinel 是 ranges::iota_view<W, Bound> 的 end() 返回的可达哨兵类型。

数据成员

成员	定义
Bound bound_	哨兵值 (仅用于阐释的成员对象*)

成员函数

std::ranges::iota_view::sentinel::sentinel

/*sentinel*/() = default;	(1)	(C++20 起)
constexpr explicit /*sentinel*/( Bound bound );	(2)	(C++20 起)

1) 值初始化 bound_。

2) 用 bound 初始化 bound_。

非成员函数

operator==(std::ranges::iota_view::iterator, std::ranges::iota_view::sentinel)

friend constexpr bool operator==( const /*iterator*/& x,                                   const /*sentinel*/& y );		(C++20 起)

返回 x.value_ == y.bound_。

!= 运算符由 operator== 合成。

此函数对普通的非限定或限定查找不可见，仅当 sentinel 是实参的关联类时，才能通过实参依赖查找找到。

operator-(std::ranges::iota_view::iterator, std::ranges::iota_view::sentinel)

friend constexpr std::iter_difference_t<W>     operator-(const /*iterator*/& x, const /*sentinel*/& y)     requires std::sized_sentinel_for<Bound, W>;	(1)	(C++20 起)
friend constexpr std::iter_difference_t<W>     operator-(const /*sentinel*/& x, const /*iterator*/& y)     requires std::sized_sentinel_for<Bound, W>;	(2)	(C++20 起)

1) 返回 x.value_ - y.bound_。

2) 返回 -(y.value_ - x.bound_ )。

这些函数对普通的非限定或限定查找不可见，仅当 sentinel 是实参的关联类时，才能通过实参依赖查找找到。
