Re: [aspectj-users] Applying @DeclareParents to annotated classes

["Andy Clement" <andrew.clement@xxxxxxxxx>]

Ok, let's see what's different, here is my application that now works perfectly:

==========8<==========
package moody;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.DeclareParents
;
import java.lang.annotation.*;

enum Mood { HAPPY, SAD, JOLLY, GRUMPY }

@Retention(RetentionPolicy.RUNTIME) @interface Coloured {}

@Coloured
class Victim { }

interface Moody {
  Mood getMood();
  void setMood(Mood mood);
}

@Aspect
class AnnotationMoodIndicator {

   public static class MoodyImpl implements Moody {
      private Mood mood = Mood.HAPPY;
      public Mood getMood() { return mood; }
      public void setMood(Mood mood) { this.mood = mood; }
   }

   @DeclareParents(value="@Coloured *",defaultImpl=MoodyImpl.class)
   private Moody implementedInterface;
}

public class MainClass {
  public static void main(String[] args) {
    Victim  Victim();
    Victim two = new Victim();

    System.err.println("one's mood is " + ((Moody)one).getMood());
    ((Moody)one).setMood(
Mood.JOLLY);
    System.err.println("two's mood is now " + ((Moody)two).getMood());
    System.err.println("one's mood is still " + ((Moody)one).getMood());
  }
}
==========8<==========

>ajc -1.5 -showWeaveInfo -d . MainClass.java
Extending interface set for type 'moody.Victim' (MainClass.java) to include 'moody.Moody' (MainClass.java)

Type 'moody.Victim' (MainClass.java) has intertyped method from '
moody.AnnotationMoodIndicator' (MainClass.java:'moody.Mood moody.Moody.getMood()')

Type 'moody.Victim' (MainClass.java) has intertyped method from 'moody.AnnotationMoodIndicator' (MainClass.java:'void moody.Moody.setMood
(moody.Mood)')

>java moody.MainClass
one's mood is HAPPY
two's mood is HAPPY
two's mood is now JOLLY
one's mood is still HAPPY

- what is the retention policy on your annotation @Audit?
- if your annotation is not in the same package as the application, you will need to fully qualify the reference in the type pattern @DeclareParents(value="@
somepackage.Coloured *",defaultImpl=MoodyImpl.class)

Sorry for the late reply. I downloaded the latest code release from the link you provided and replaced all the jars used in my build. Unfortunately it appears as though it is still not working. When I take the @Audit annotation off the pattern it starts working again.

Ok Scott ...

Are you able to download and try the latest AspectJ?  Fresh off the presses, from our download page or directly through this link:

  http://www.eclipse.org/downloads/download.php?file=/technology/aspectj/dev/aspectj-DEVELOPMENT-20060329133605.jar

This *will* fix your annotation problem.  It may also affect the other problem where you needed to create the proxy interface - are you able to try it in that situation too?

cheers,

Andy.
