Llamadas basic_ios::swap(rhs) para intercambiar todos los miembros de datos de la clase base, excepto rdbuf() y swaps los valores de los contadores de
gcount() entre *this y rhs. Esta función de intercambio es protegida: se llama a las funciones de intercambio de las clases de flujo de entrada intercambiables std::basic_ifstream y std::basic_istringstream, que sabe cómo intercambiar correctamente los streambuffers asociados .Original:
Calls basic_ios::swap(rhs) to swap all data members of the base class except for rdbuf(), and swaps the values of the
gcount() counters between *this and rhs. This swap function is protected: it is called by the swap functions of the swappable input stream classes std::basic_ifstream and std::basic_istringstream, which know how to correctly swap the associated streambuffers.The text has been machine-translated via Google Translate.

#include <sstream> #include <iostream> #include <utility> int main() { std::istringstream s1("hello"); std::istringstream s2("bye"); s1.swap(s2); // OK, istringstream has a public swap() std::swap(s1, s2); // OK, calls s1.swap(s2) // std::cin.swap(s2); // ERROR: swap is a protected member std::cout << s1.rdbuf(); }
Output:
hello
