An Upload object is usually created by calling [[Collection::createUpload()]]. Note: instance of this class is 'single use' only. Do not attempt to use same Upload instance for multiple file upload. Usage example: php $document = Yii::$app->mongodb->getFileCollection()->createUpload() ->addContent('Part 1') ->addContent('Part 2') ... ->complete();
