The pattern is pretty much always: if ( thing not in cache ) { do expensive calculation / data loading put thing in cache for X minutes } get thing from cache (and return it or do something to it) Since memoize seems to be 'forever' and caching in general smells of mutable state, I wondered how folks are tackling this sort of thing in Clojure? Are you simply dropping down to Java libraries and being 'non-functional' or is there some more idiomatic approach available? -- Sean A Corfield -- (904) 302-SEAN Railo Technologies, Inc. -- http://getrailo.com/ An Architect's View -- http://corfield.org/ "If you're not annoying somebody, you're not really alive." -- Margaret Atwood -- You received this message because you are subscribed to the Google Groups "Clojure" group.
