[aspectj-users] Capturing setting inside List

[André Dantas Rocha <ad-rocha@xxxxxxxxxx>]

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
