将 basic_const_iterator 与另一个值进行比较。

!= 运算符由 operator== 合成。

I 满足 /*different-from*/ < basic_const_iterator > 当且仅当 std:: same_as < I, basic_const_iterator < Iter >> 为假。

目录

参数

s - Iter 的哨兵值
y - 用于比较的值

返回值

1) base ( ) == s
2) base ( ) < y. base ( )
3) base ( ) > y. base ( )
4) base ( ) <= y. base ( )
5) base ( ) >= y. base ( )
6) base ( ) <=> y. base ( )
7) base ( ) < y
8) base ( ) > y
9) base ( ) <= y
10) base ( ) >= y
11) base ( ) <=> y

注释

当 Iter 满足 sentinel_for < Iter > 模型时，可使用重载 ( 1 ) 来比较两个 basic_const_iterator<Iter> 值。
