Cache decorator

>>> def key(method, self):
...     return method.__name__

>>> from eea.cache import cache
>>> @cache(key, dependencies=["frontpage"])
... def myMethod(num):
...     return num*num

Lets clear any running memcache

>>> from lovely.memcached.event import InvalidateCacheEvent
>>> from zope.event import notify
>>> notify(InvalidateCacheEvent(raw=True, dependencies=['frontpage']))

Our myMethod will now be cached with the key returned from the method ‘key’ and with dependency ‘frontpage’.

>>> myMethod(2)
4
>>> myMethod(3)
4

>>> notify(InvalidateCacheEvent(raw=True, dependencies=['frontpage']))
>>> myMethod(3)
4
