Re: [armedbear-devel] Passing lisp objects from java to lisp

Greetings, If I have a lisp function as follows:     (defun myfun (a b)         (+ a b)) I want to be able to call it from lisp or java.  In other words I don't want the lisp side to have to use jobject-lisp-value. Therefore, from the java side, how do I take a java object and translate into a lisp object so that when I call the execute method the lisp function doesn't need jobject-lisp-value?

JavaObject.getInstance(javaObj, true)

You also have the option to use the JSR-223 API that does Java<->Lisp conversions for you:

Invocable invocable = (Invocable) lispEngine; //obtained like in the abcl examples invocable.invokeFunction("pkg:myfun", 12, 34); //returns 46
