public member function

std::basic_istringstream::swap

void swap (basic_istringstream& x);

Swap internals

Exchanges all internal data between x and *this.

Internally, the function calls basic_istream::swap and then calls the member swap of the associated basic_stringbuf object.

Parameters

x: Another basic_istringstream object with the same template parameters (charT, traits and Alloc).

Return Value

none

Example

// swapping istringstream objects
#include <string>       // std::string
#include <iostream>     // std::cout
#include <sstream>      // std::istringstream

int main () {

  std::istringstream foo ("100");
  std::istringstream bar ("200");

  foo.swap(bar);

  int val;

  foo >> val; std::cout << "foo: " << val << '\n';
  bar >> val; std::cout << "bar: " << val << '\n';

  return 0;
