If you're interested, here is a starting point for experimenting with any variations you want (invalidate a specific entry, changeable maxsize, pickle/unpickle, expiration of entries after a specific time, inspection of the internal contents, ability to inject known values, testing whether a specific argument tuple is in the cache, logging of cache access, or just about anything you could do with a regular dictionary):
class LRU(OrderedDict):
def __init__(self, func, maxsize=128):
self.maxsize = 128
self.func = func
def __call__(self, *args):
if args in self:
value = self[args]
self.move_to_end(args)
return value
value = self.func(*args)
if len(self) >= self.maxsize:
self.popitem(False)
self[args] = value
return value |
