Subject:    [aspectj-users] Capturing setting inside List


Suppose I have this classes...

public class A implement Serializable {
  List list = new ArrayList();
  public add(Object o) {
    list.add(o);
  }
}

public class B {
  int x;
  setX(int x) {
    this.x = x;
  }
}

... and a main method:

public void main(String[] args) {
  a1 = new A();
  b1 = new B();
  a1.add(b1);

  a2 = new A();
  b2 = new B();
  a2.add(b2);

  b1.setX(3);  // a1 affected
}

I would like to serialize the A object every time an element in his List is
modified (in this case, only a1 will be serialized).
Is it possible to intercep this pointcut using AspectJ?

Thanks,

André_______________________________________________
