std::front_insert_iterator est un itérateur de sortie qui est précédée d'éléments dans un conteneur pour lequel il a été construit, en utilisant la fonction du conteneur push_front() membre lorsque l'itérateur (que ce soit déréférencé ou non) est assigné. L'incrémentation du std::front_insert_iterator est un no-op .

Original:

std::front_insert_iterator is an output iterator that prepends elements to a container for which it was constructed, using the container's push_front() member function whenever the iterator (whether dereferenced or not) is assigned to. Incrementing the std::front_insert_iterator is a no-op.
