How to get a clojure handle on a Java static method, similar to_ memfn_ Methods for Java instances?

To handle the Java instance methods that we can call later, we can call the memfn function:

user=> (def g (memfn Integer/toString))
#'user/g

user=> (g 789)
"789"

This does not work for Java static methods:

user=> (def g (memfn Integer/toHexString))
#'user/g

user=> (g 789)
IllegalArgumentException No matching method found: toHexString for class java.lang.Long  clojure.lang.Reflector.invokeMatchingMethod (Reflector.java:52)

user=> (g)
ArityException Wrong number of args (0) passed to: user$g  clojure.lang.AFn.throwArity (AFn.java:437)

How do we get the handle to the Java static method so that it can be called later?

Solution

(defn g [x](Integer / toHexString x))……？ You can wrap it in a macro if you like, but there's nothing to do:

(defmacro static-fn [f] `(fn [x#] (~f x#)))
(def g (static-fn Integer/toHexString))
