std::ostreambuf_iterator est un itérateur de sortie en un seul passage qui écrit caractères successifs dans l'objet std::basic_streambuf pour lequel il est construit. L'opération d'écriture proprement dite s'effectue lorsque l'itérateur (si déréférencé ou non) est assigné. L'incrémentation du std::ostreambuf_iterator est un no-op .Original:
std::ostreambuf_iterator is a single-pass output iterator that writes successive characters into the std::basic_streambuf object for which it was constructed. The actual write operation is performed when the iterator (whether dereferenced or not) is assigned to. Incrementing the std::ostreambuf_iterator is a no-op.The text has been machine-translated via Google Translate.
