how can i register a java function in lua ?

hello everyone !
how can i register a java function with Register ?
Is it possible to register functions already created in the main class or inside other classes?

I don't think there is a universal way to do this. But pushing the corresponding object, setGlobal to assign it to a global variable and wrapping it up with a Lua function should work:

Function<String, String> f = (s) -> s + s;
L.push(f);
L.setGlobal("obj");
L.run("function f(s) obj:apply(s) end")
