[aspectj-users] Polymorphism & Introductions

["Aamir Raheem" <aamir_raheem@xxxxxxxxxxx>]

Hi,

 

Consider the following simple program:

 

public class Shape {
 void draw() {
  System.out.println("Shape.draw() called");
 }
}

 

public class Line extends Shape { 
}

 

public aspect AnAspect {
 void Line.draw() {
  System.out.println("Line.draw() called");
 }
}

 

public class Main {
 public static void main(String[] args) {
  Shape s = new Line();
  s.draw();
 }
}

 

The AJDT 1.1.12 for Eclipse 3.0.0 generates following output for the above program:

 

Shape.draw() called

 

I want to know why polymorphism does not work here?

 

Thanks and Regards,
