Ability to clear cache of memoized functions #228

Open jiffyclub opened 9 years ago

jiffyclub commented 9 years ago

Function's decorated with functools' lru_cache have a cache_clear() function attached to them so that the cache can be manually invalidated. It'd be useful to me if toolz's memoize function did the same thing.

Yeah, it should definitely be possible to clear a cache. I think it is sufficient to expose func, cache, and key as attributes of the memoized function.

Unlike lru_cache, memoize can accept a cache object from the user. Giving the user direct access to that is more flexible.

It would also be useful to do a "cache refresh", on a given call, ie.:

  1. clear from cache specifically the key associated to the given call
  2. do a "regular call" (obtain result from decorated function, save it into the cache & return it)
