插入给定的 value 到迭代器。
1) 导致 container->push_front(value)
2) 导致 container->push_front(std::move(value))
参数
| value | - | 要插入的值 |
返回值
*this
示例
运行此代码
#include <iostream> #include <iterator> #include <deque> int main() { std::deque<int> q; std::front_insert_iterator< std::deque<int> > it(q); for (int i=0; i<10; ++i) it = i; // 调用 q.push_front(i) for (auto& elem : q) std::cout << elem << ' '; }
输出：
9 8 7 6 5 4 3 2 1 0
