java - Make a class that extends a class with overriding in clojure -


i've got pretty simple java code:

public class messagelistenerexample extends listeneradapter {     @override     public void onmessagereceived(messagereceivedevent event)     {         // event     } }

however, can't seem understand how turn code clojure code. docs , articles confusing. i'd happy see more examples too. i'm interested in using implements.

depending on need do, few options:

  1. if need extend class (other object) in clojure, can using gen-class, see https://clojuredocs.org/clojure.core/gen-class. preferably using ns macro, like
(ns your.class.name     :extends whatever.needs.to.be.extended)  (defn -methodyouoverride   ; mind dash - it's important     [...] ...)

i wouldn't recommend going down path unless absolutely necessary. getting compilation right (including aot compilation) tricky. , in end still need use java interop work objects of class, not sure it's worth hassle, brings me to:

  1. code in java , use java interop work it.

  2. if need create instance of object implements interface, it's easier:

(reify    interfaceyouimplement    (methodyouimplement [..] ..)

i use around code, it's nicer coding in java.
