std::back_insert_iterator es un OutputIterator que añade a un recipiente para la que fue construido, con la función del contenedor push_back() miembro cada vez que el iterador (si anula la referencia o no) está asignado. El incremento del std::back_insert_iterator es un no-op .

Original:

std::back_insert_iterator is an OutputIterator that appends to a container for which it was constructed, using the container's push_back() member function whenever the iterator (whether dereferenced or not) is assigned to. Incrementing the std::back_insert_iterator is a no-op.
