std::insert_iterator est un itérateur de sortie qui insère des éléments dans un récipient pour lequel elle a été construite, à l'endroit pointé par l'itérateur fourni, en utilisant la fonction de l'élément de conteneur insert() chaque fois que l'itérateur (si déréférencé ou non) est assigné. L'incrémentation du std::insert_iterator est un no-op .
Original:
std::insert_iterator is an output iterator that inserts elements into a container for which it was constructed, at the position pointed to by the supplied iterator, using the container's insert() member function whenever the iterator (whether dereferenced or not) is assigned to. Incrementing the std::insert_iterator is a no-op.
