void swap(basic_ostream& rhs);
(desde C++11)
Llamadas basic_ios::swap(rhs) para intercambiar todos los miembros de datos de la clase base, a excepción de rdbuf(), entre *this y rhs. Esta función de intercambio es protegida: se llama a las funciones de intercambio de las clases stream de salida intercambiables std::basic_ofstream y std::basic_ostringstream, 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(), 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.
