std::experimental::make_ostream_joiner
来自 cppreference.cn
< cpp | experimental | ostream joiner
| 定义于头文件 <experimental/iterator> |
||
| template< class CharT, class Traits, class DelimT > std::experimental::ostream_joiner<std::decay_t<DelimT>, CharT, Traits> |
(库基础 TS v2) | |
创建 ostream_joiner 对象，从函数实参的类型推导模板实参。
[edit] 参数
| os | - | 将迭代器关联到的 basic_ostream 对象 |
| delimiter | - | 分隔符 |
[edit] 返回值
一个 ostream_joiner 对象，如同通过 std::experimental::ostream_joiner<std::decay_t<DelimT>, CharT, Traits>(os, std::forward<DelimT>(delimiter)) 创建一样
[edit] 示例
运行此代码
#include <experimental/iterator> #include <iostream> #include <vector> int main() { std::vector<int> x{1, 2, 3, 4}; std::copy(x.begin(), x.end(), std::experimental::make_ostream_joiner(std::cout, ", ")); }
输出
1, 2, 3, 4
