I'm trying to generate a Java class from Clojure with gen-class, but
without much success. I've got the following code:
(ns p.C (:gen-class :methods [[m [Object] void]]))
(defn -m [o] (println (.. o getClass getName)))
The signature of the m method is correct:
javap p.C
public class p.C extends java.lang.Object{
public static {};
public p.C();
public int hashCode();
public boolean equals(java.lang.Object);
public java.lang.String toString();
public java.lang.Object clone();
public void m(java.lang.Object);
public static void main(java.lang.String[]);
}
But when I try to call the method, I get the following exception:
NativeException: java.lang.IllegalArgumentException: Wrong number of
args passed to: C$-m
from clojure/lang/AFn.java:469:in `throwArity'
from clojure/lang/AFn.java:76:in `invoke'
from p.C:-1:in `m'
from sun/reflect/NativeMethodAccessorImpl.java:-2:in `invoke0'
from sun/reflect/NativeMethodAccessorImpl.java:39:in `invoke'
from sun/reflect/DelegatingMethodAccessorImpl.java:25:in `invoke'
from java/lang/reflect/Method.java:597:in `invoke'
...
What's going on?
Also, can somebody give an example of a gen-class call that specifies:
- a static method
- a method with an array among the parameters.
Cheers,
Michiel de Mare
