I found this script at http://www.pygame.org/wiki/LazyImage...arent=CookBook
And I can't quite figure out how it works. I was wondering if someone
could clarify it for me.
The Code is:
import pygame
import weakref
class ResourceControl ler(object):
def __init__(self, loader):
self.__dict__.u pdate(dict(
names = {},
cache = weakref.WeakVal ueDictionary(),
loader = loader
))
def __setattr__(sel f, name, value):
self.names[name] = value
def __getattr__(sel f, name):
try:
img = self.cache[name]
except KeyError:
img = self.loader(sel f.names[name])
self.cache[name] = img
return img
class ImageController (ResourceContro ller):
def __init__(self):
ResourceControl ler.__init__(se lf, pygame.image.lo ad)
My question is why does the __setattr__ set the value to
self.names[name] instead of self.cache[name]?
