Clojurians Log v2

Maybe helping GraalVM along with a reflection.json helps?

{
    "name": "foo.bar.XListener",
    "queryAllDeclaredConstructors": true,
    "queryAllPublicConstructors": true
  },

What does the Clojure compiler say when you set:

(set! *warn-on-reflection* true)

If Clojure doesn't complain, it's maybe a different issue

It does complain 🙂

Then you can likely fix it within Clojure itself without adding reflection config?

Let me double check what it thinks the problem is...

Yes @rahul080327 it does work to do that, and that might be my fallback approach.

yeah eliminating it via a typehint should be nicer

Yeah so the problem I guess is that in the call site we use a .instanceMethod type of call, and that function that looks roughly like this:

(defn ->top-secret
  [listener]
  (->> listener
       .getFunctions
       parsed-fns->internal-format
       (into [])))

*warn-on-reflection* doesn't like that one, but I have 25 different listeners without a common base class to hint against

you can add a type-hint to the listener argument

I might have to pass it the ->top-secret function or a wrapped getFunctions instead I think? because the caller does not have access to my 25 different types of Listener and there's no commonality between them

But I could construct a type-hinted getFunctions wrapper per Listener

maybe 😮

or maybe there can be an interface introduced?

It's generated code so I'm a bit tied up on the java side - but could I do something in clojure?

you can't retrofit an interface to JVM types in Clojure, but you can introduce protocols. You'll have to extend it to your 25 concrete classes though, which doesn't buy you much

All right, thanks so much for the help I'll try to pass something with type hints 🙂

Otherwise I guess I dig into the classes and generate the reflect config

Maybe you fellows know a good programmatic way to access a namespaces' imports? 🙂

(ns-imports *ns*)
