Der Umzug Konstruktor verwendet basic_ios<CharT, Traits>::move(rhs) alle basic_ios Mitglieder zu bewegen, mit Ausnahme der rdbuf() von rhs in *this. Dieser Schritt Konstruktor geschützt ist: es wird durch die Bewegung Konstruktoren von beweglichen Ausgabe-Stream-Klassen aufgerufen std::basic_ofstream und std::basic_ostringstream, die wissen, wie man richtig zu bewegen das zugehörige streambuffer .
Original:
The move constructor uses basic_ios<CharT, Traits>::move(rhs) to move all basic_ios members, except for the rdbuf(), from rhs into *this. This move constructor is protected: it is called by the move constructors of movable output stream classes std::basic_ofstream and std::basic_ostringstream, which know how to correctly move the associated streambuffer.

#include <sstream>
#include <utility>
#include <iostream>
int main()
{
//  std::ostream myout(std::cout);              // ERROR: copy ctor is deleted
    std::ostream myout(std::cout.rdbuf());      // OK: shares buffer with cout
//  std::ostream s2(std::move(std::ostringstream() << 7.1));       // ERROR: move constructor
                                                                   // is protected
    std::ostringstream s2(std::move(std::ostringstream() << 7.1)); // OK: move ctor called
                                                                   // through the derived class
    myout << s2.str() << '\n';
}
