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 cacheable filename, and the filename must not be already cached. r TFr" r# �__name__� __loader__N�__spec__� get_source) r r r) r* �get�loaderr2 �getattr� functools�partial)r r �namerA �specr? � get_linesr r r r � s* � r )N) �__doc__rC r/ r r3 �__all__r r r r r r r r r r r �<module> s C
