> You just discard all references to an object. And then afterwards I called (makea), creating a new 'a object. But then why does it throw an exception when I deref it?
I searched the archives and learned that my intended coding style (using global vars) isn't idiomatic: http://groups.google.com/group/clojure/msg/e40c4bed7dc28ebb so then I settled with the following code, to handle the db and server variables, which i sometimes redefine. in case of freeing the objects, then i'd reset! them to nil. i hope this is a good method of managing global vars that are accessible from everywhere. (defn create-db [] (EmbeddedGraphDatabase. (:dir-db (:directories *config*)))) (defn create-server [] (run-jetty (var routes) (:jetty *config*))) (defonce db (atom (create-db))) (defonce server (atom (create-server))) (defn stop "stop the servers." [] (.stop @server) (.shutdown @db)) (defn restart "restart the servers." [] (stop) (reset! db (create-db)) (reset! server (create-server))) -- You received this message because you are subscribed to the Google Groups "Clojure" group.
