std::ostreambuf_iterator ist ein Single-Pass-Output-Iterator, die aufeinanderfolgende Zeichen schreibt in den std::basic_streambuf Objekt, für das es konstruiert wurde. Die tatsächliche Schreiboperation durchgeführt wird, wenn der Iterator (ob oder nicht dereferenziert) zugeordnet ist. Inkrementieren des std::ostreambuf_iterator ist ein 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.
