std::basic_stringbuf<CharT,Traits,Allocator>::operator=
来自 cppreference.cn
< cpp | io | basic stringbuf
| std::basic_stringbuf& operator=( std::basic_stringbuf&& rhs ); |
(1) | (since C++11) |
| std::basic_stringbuf& operator=( const std::basic_stringbuf& rhs ) = delete; |
(2) | |
1) 移动赋值运算符：将 rhs 的内容移动到 *this。移动后，*this 拥有与 rhs 之前持有的关联字符串、打开模式、区域设置和所有其他状态。 std::basic_streambuf 中 *this 的六个指针保证与移动前的 rhs 中的对应指针不同，除非为空。

| rhs | - | 另一个 basic_stringbuf，其内容将被移动 |
[编辑] 返回值
*this
[编辑] 示例
运行此代码
#include <iostream> #include <sstream> #include <string> int main() { std::istringstream one("one"); std::ostringstream two("two"); std::cout << "Before move, one = \"" << one.str() << '"' << " two = \"" << two.str() << "\"\n"; *one.rdbuf() = std::move(*two.rdbuf()); std::cout << "After move, one = \"" << one.str() << '"' << " two = \"" << two.str() << "\"\n"; }
输出
Before move, one = "one" two = "two" After move, one = "two" two = ""
