The module loader will be asked for the source only when getlines is called, not immediately. If there is an entry in the cache already, it is not altered. :return: True if a lazy load is registered in the cache, otherwise False. To register such a load a module loader with a get_source method must be found, the filename must be a cachable filename, and the filename must not be already cached. r TFr r! � __loader__�__name__� get_sourceN)r r r' r( �get�getattr� functools�partial)r r �name�loaderr; � get_linesr r r r) � s r) )N)N)N)N) �__doc__r> r. r r2 �__all__r r r r r r r) r r r r �<module> s A
