[aspectj-users] Intertype declaration with methods returning instances of the class itself
|
Hi all,
I wonder if, in Intertype declaration, is it possible for me to add a method
to any class with a common characteristic (annotated with something, for
example, that returns an instance of the class itself? To better understand
what I want, let me show an example:
@MyAnnotation
public class A {
}
@MyAnnotation
public class B {
}
public aspect MyAspect {
// this does not compile
public void (@MyAnnotation *).foo() {
}
// So, I have tried this:
declare parents : (@MyAnnotation *) implements MyInterface;
interface MyInterface {
}
// this works ok
public void MyInterface.foo() {
System.out.println("In foo");
}
// But this does not compile! I would like to create a method returning an
// instance of the class itself. Any ideas about how to do this?
public (@Singleton *) getInstance() {
return new (@Singleton *)();
}
}
Is the previous possible?
Thanks in advance. Cheers,
Paulo Zenida
