Has anybody written a Memoize-like decorator for Zope?
I imagine that it could be a nice feature to have a standard decorator
for Zope that would cache results in a _v_ volatile variable.
I usually do it a bit like this::
def _cache_it(self, meth, *args, **kwargs):
cache_name = '_v_%s' % meth.__name__
if not hasattr(self, cache_name):
result = meth(*args, **kwargs)
setattr(self, cache_name, result)
return getattr(self, cache_name)
def _some_function(self):
# do expensive calculations and return result
return 42
def some_function(self, *args, **kwargs):
"Returns cached values"
return self._cache_it(self._some_function, *args, **kwargs)
But I guess that there must be someone who has allready written a more
generic way to do it via generators?
