Hi all,
I have a Java Map contains Map of Maps/List (JSON like map) and have
to convert to Clojure map (This happens at Java - Clojure Interop), So
I have written a converter function 'as-clj-map' by modifying the
clojure walk functions, It works fine, but consume lot of cpu when the
data structure is quit big. Any suggestions to improve this code?
(defn walk-coll [inner outer form]
(cond
(instance? java.util.List form) (outer (into [] (map inner
form)))
(instance? java.util.Map form) (outer (into {} (map inner
form)))
:else (outer form)))
(defn postwalk-coll [f form]
(walk-coll (partial postwalk-coll f) f form))
(defn as-clj-map [m]
(let [f (fn [[k v]] (if (string? k) [(keyword k) v] [k v]))]
(postwalk-coll (fn [x] (if (instance? java.util.Map x) (into {}
(map f x)) x)) m)))
Thanks and regards.
