Это обезжиренная версия класса;Надеюсь, это может служить.Эта версия все еще сохраняет правильную реализацию flush ().
В оригинальной версии есть оптимизация для процесса in-mem (надеюсь, он все еще работает после вырезания какой-то части).Источник содержит CRC32 от Apache и соответствующее уведомление о лицензии.
