Appels basic_ios::swap(rhs) d'échanger toutes les données membres de la classe de base, à l'exception des rdbuf(), entre *this et
rhs. Cette fonction de permutation est protégé: il est appelé par les fonctions d'échange des classes interchangeables flux de sortie std::basic_ofstream et std::basic_ostringstream, qui savent correctement permuter les streambuffers associés .Original:
Calls basic_ios::swap(rhs) to swap all data members of the base class, except for rdbuf(), between *this and
rhs. This swap function is protected: it is called by the swap functions of the swappable output stream classes std::basic_ofstream and std::basic_ostringstream, 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::ostringstream s1("hello"); std::ostringstream s2("bye"); s1.swap(s2); // OK, ostringstream has a public swap() std::swap(s1, s2); // OK, calls s1.swap(s2) // std::cout.swap(s2); // ERROR: swap is a protected member std::cout << s1.str() << '\n'; }
