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
Run this code
#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"
