In another thread, someone just indicated that a closed-over variable chews up permgen. Is this true?
I had been under the impression that keywords didn't get garbage-collected, so runtime generation with (keyword foo) ought to be used sparingly, but that was it. Perhaps the scenario was something along the lines of (defn make-generator [] (let [a (atom 0)] (fn [] (swap! a inc) @a))) (def my-generator (make-generator)) user=> (my-generator) 1 user=> (my-generator) 2 user=> In this case, a closed-over atom is referenced by a function that's bound to a global var, my-generator. This won't be garbage-collected so long as my-generator isn't un/redef'd. Even so it shouldn't be permgen, technically speaking; just indirectly referenced by a loaded class and so ineligible for GC by more "ordinary" criteria. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
