[aspectj-users] add instance members to a class
|
Hi,
I'm just learning about AspectJ. I haven't been able to determine if
I can apply it to my problem.
The problem is to add an instance member, together with
getters/setters, to certain existing classes. This seems to be an
example of a crosscutting concern.
So far, I have managed with AspectJ only to produce classes with new
static members.
Is it possible with AspectJ to create an annotation, say @Labelled, so that
@Labelled
public class LabelledClass extends PlainClass{
}
so that instances of LabelledClass will have their own private String
member "itsLabel", with a getter "getLabel()", and a setter
"setLabel()". That is, so that LabelledClass effectively implements
interface LabelledInterface{
String getLabel();
void setLabel( String label );
}
How would one go about this? Is something like this possible?
If this kind of thing isn't possible, where can I find passages in the
documentation that would clarify the situation?
Thanks!
