递增或递减迭代器。
令 inner_
为底层迭代器并且 Base
为仅用于阐述的成员类型,
等价于:
1) ++inner_; return *this;
2) auto tmp = *this; ++*this; return tmp;
3) --inner_; return *this;
4) auto tmp = *this; --*this; return tmp;
5) inner_ += n; return *this;
6) inner_ -= n; return *this;
参数
n | - | 相对于当前位置的偏移量 |
返回值
1,3,5,6) *this
2,4) *this 被修改前的副本
