hi,
its not working.
*java class:*
public class UserAttributes implements Interceptable {
@LIST(3)
private ArrayList<String> alias;
public static void main(String[] argv) {
UserAttributes u = new UserAttributes();
u.alias = new ArrayList();*// point 1*
}
}
*point cut:*
public aspect INAspect {
pointcut annCut(LIST in) : set(@LIST* (*) * ) && @annotation(in) &&
target(java.util.List+);
* //this should return the new MYList(); I also want the annotation to be
accessible here (i.e.. cutting :: point 1).*
after(LIST in) :annCut(in) && within(com.pg.interceptor.Interceptable+)
{
System.out.println("**annotation " + thisJoinPoint + " ann:"
+ in.value());
// return new PGList();
}
any ideas please? :(
