For the benefit of others, since this took me a while to understand...
When using gen-class to extend or implement a superclass with
overloaded methods, use a single multi-arity function to override the
overloaded methods in the superclass:
expmeth/ClassA.java:
package expmeth;
public class ClassA {
public void hello() {
System.err.println("hello from Java!");
}
public void hello(int x) {
System.err.println("hello from Java " + x);
}
}
expmeth/TestMe.clj:
(ns expmeth.TestMe
(:gen-class
:extends expmeth.ClassA
:exposes-methods {hello helloSuper}))
(defn -hello
([this]
(.helloSuper this)
(println "hello from clojure!"))
([this x]
(.helloSuper this x)
(println "hello from clojure..." x)))
testing:
(.hello (expmeth.TestMe.) 17)
(.hello (expmeth.TestMe.) )
