std::basic_stringbuf<CharT,Traits,Allocator>::swap: std::basic_stringbuf<CharT,Traits,Allocator>::swap

NAME

std::basic_stringbuf<CharT,Traits,Allocator>::swap - std::basic_stringbuf<CharT,Traits,Allocator>::swap

Synopsis


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"
