Is there a way to be notified when a clojure future finishes?

Question

Is there a way to set a watch on a future so that it triggers a callback when it is done?

something like this?

> (def a (future (Thread/sleep 1000) \"         


        

Answer 1

Instead of adding additional time with Thread/Sleep , I'm leveraging on the fact that @future-ref for any reference to the future will wait until the future is done.

(defn  wait-for
  [futures-to-complete]
  (every? #(@%) futures-to-complete))
