    help with poincut for annotation parameter values

      I'd like to add mixins to all the classes annotated with:

      @Mixins(value={Mixin1.class, Mixin2.class})
      public class TargetClass {
      }

      My understanding is that I have to define 2 aspects for Mixin1 and Mixin2 classes. But I can't work out pointcuts for them. Could anybody help me?

          As far as I know you can only set pointcuts for an annotation, but not for its attributes. So you have to intercept all @Mixins annotations and then you can check out which attributes are set in your aspect/interceptor:


          MethodInvocation methodInvocation = (MethodInvocation) invocation;
//get your annotation
@Mixins mixinAnnotation = methodInvocation.getMethod().getAnnotation(ContainerSide.class);
//get the value attribute
class[] someClasses = mixinAnnotation.value();
doSomethingSpecial();


          This was just a quick example and might not work like that, but it shows the way to do it.
          Maybe this example helps somehow.

            DerMas, thanks for help.
            I'm afraid what I'm looking for is actually not supported. Dynamic interception won't help 'cause I have to reflect aspectized classes.
