1,2) Construye un iterador de fin de flujo.

3) Inicializa el iterador y almacena el valor de is. rdbuf ( ) en un miembro de datos. Si is. rdbuf ( ) es nulo, entonces se construye un iterador de fin de flujo.

4) Inicializa el iterador y almacena el valor de s en un miembro de datos. Si s es nulo, entonces se construye un iterador de fin de flujo.

5) Llame efectivamente a (3) con el puntero


        streambuf_type*

que p contiene.

6) El constructor de copia es trivial y está explícitamente predeterminado.

El constructor de copia está efectivamente declarado de forma implícita y no se garantiza que sea trivial.

(until C++11)
