(3) (desde C++11)
1)
Construye el objeto basic_istream, asignar valores iniciales a la clase base llamando basic_ios::init(sb). El valor de gcount() se inicializa a cero .
Original:
Constructs the basic_istream object, assigning initial values to the base class by calling basic_ios::init(sb). The value of gcount() is initialized to zero.

3)
El constructor movimiento copia el valor de gcount() de rhs, establece el gcount () valor de RHS a cero, y utiliza basic_ios<charT, traits>::move(rhs) 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 entrada y std::basic_ifstream std::basic_istringstream, que sabe cómo mover correctamente el streambuffer asociado .
Original:
The move constructor copies the value of gcount() from rhs, sets the gcount() value of rhs to zero, and 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 input stream classes std::basic_ifstream and std::basic_istringstream, which know how to correctly move the associated streambuffer.

#include <sstream>
#include <iostream>
int main()
{
    std::istringstream s1("hello");
    std::istream s2(s1.rdbuf());                        // OK: s2 shares the buffer with s1
 
//    std::istream s3(std::istringstream("test"));      // ERROR: move constructor is protected
//    std::istream s4(s2);                              // ERROR: copy constructor is deleted
    std::istringstream s5(std::istringstream("world")); // OK: move ctor called by derived class
 
    std::cout << s2.rdbuf() << ' ' << s5.rdbuf() << '\n';
}

Output:

hello world
