Solussd is absolutely correct, but maybe even more simplistic (or easier to grasp) explanation would be to use metadata if you don't want the additional (meta)data to change the equality semantics of the map, for example:
(def test-desc1 {:number-of-threads 10}) (def test-desc2 ^{:integration true} {:number-of-threads 10}) (def test-desc3 {:number-of-threads 10 :integration true}) (= test-desc1 test-desc2) ;; returns true (= test-desc1 test-desc2 test-desc3) ;; returns false, because while the first two vars reference equal values, the third one doesn't Dňa štvrtok, 29. januára 2015 16:10:34 UTC+1 Jonathon McKitrick napísal(-a): > > Is there a rule of thumb or set of use cases when metadata is a more > elegant solution than simply adding more entries to a map or record? > -- You received this message because you are subscribed to the Google Groups "Clojure" group.
