    what happened to $r?

    herkules000 Sep 28, 2009 6:25 AM

      Shouldn't that work?

      class Foo {
 Object foo() {
 return new Object();
 }
}

public class Main {
 public static void main(String[] args) throws NotFoundException, CannotCompileException {
 ClassPool cp = ClassPool.getDefault();
 CtClass foocls = cp.get("jatest.Foo");
 CtMethod m = foocls.getMethod("foo", "()Ljava/lang/Object;");
 m.insertBefore("$r x = new Object();");
 }
}


      I get: compile error: no such class: $r

          Just for the record, I'd like to take a whack at this one.

           

          Someone can correct me if I am wrong (which might be rare looking at the activity in this forum) but there are 2 errors in my opinion:

           

          1.) You are using a local variable 'x' without adding the local variable first using addlocalvariable() function.

          2.) $r is not available to code added using insertBefore() function. Switching insertBefore() call to insertAfter() call should resolve this bug.

              correction: it turns out that one can declare local variables directly via calls to insertBefore/insertAfter although it should be available only within that code block
