`template< class CharT, class Traits = std::char_traits<CharT>> class ostreambuf_iterator : public std::iterator<std::output_iterator_tag, void, void, void, void>`

std::ostreambuf_iterator é um iterador de saída de uma única passagem que escreve personagens sucessivos no objeto std::basic_streambuf para o qual foi construído. A operação de gravação real é executada quando o iterador (se dereferenced ou não) é atribuído. Incrementando a std::ostreambuf_iterator é um não-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.

Numa aplicação típica, os membros de dados somente de std::ostreambuf_iterator são um ponteiro para o std::basic_streambuf associado e um sinalizador booleano indicando se o final da condição de arquivo foi atingido.

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.
