| protected: void swap(basic_istream& rhs); |
(depuis C++11) | |
Appels basic_ios::swap(rhs) d'échanger toutes les données membres de la classe de base à l'exception des rdbuf(), et échange les valeurs des compteurs
gcount() entre *this et rhs. Cette fonction de permutation est protégé: il est appelé par les fonctions d'échange des classes de flux d'entrée interchangeables std::basic_ifstream et std::basic_istringstream, 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(), 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(); }
Résultat :
hello
