El constructor movimiento basic_ios<CharT, Traits>::move(rhs) utiliza para mover todos los miembros basic_ios, a excepción de la rdbuf(), de rhs en *this. Este constructor movimiento está protegido: es llamado por los constructores de muebles se mueven las clases de flujo de salida std::basic_ofstream y std::basic_ostringstream, que sabe cómo mover correctamente el streambuffer asociado .

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.
