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.

Dans une application typique, les éléments de données sont uniquement des std::ostreambuf_iterator un pointeur vers la std::basic_streambuf associé et un indicateur booléen indiquant si la fin de l'état de fichier a été atteinte .

Original:

In a typical implementation, the only data members of std::ostreambuf_iterator are a pointer to the associated std::basic_streambuf and a boolean flag indicating if the the end of file condition has been reached.
