std::basic_stringbuf::swap
性病：基本[医]字符串：：交换
| void swap( std::basic_stringbuf& rhs ) | | (since C++11) |
|---|
交换状态和内容*this和rhs...
参数
| rhs | - | another basic_stringbuf |
|---|
返回值
%280%29
注记
此函数在交换时自动调用。std::stringstream对象时，很少有必要直接调用它。
例
二次
#include <sstream>
#include <string>
#include <iostream>
int main()
{
std::istringstream one("one"
std::ostringstream two("two"
std::cout << "Before swap, one = \"" << one.str() << '"'
<< " two = \"" << two.str() << "\"\n";
*one.rdbuf()->swap(*two.rdbuf()
std::cout << "Before swap, one = \"" << one.str() << '"'
<< " two = \"" << two.str() << "\"\n";
}
二次
产出：
二次
Before swap, one = "one" two = "two"
Before swap, one = "two" two = "one"
二次
