void swap( std::basic_stringbuf& rhs ) | (since C++11) |
Swaps the state and the contents of *this and rhs.
Parameters
| rhs | - | another basic_stringbuf |
Return value
(none).
Notes
This function is called automatically when swapping std::stringstream objects, it is rarely necessary to call it directly.
Example
#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";
}Output:
Before swap, one = "one" two = "two" Before swap, one = "two" two = "one"
