Re: [aspectj-users] Identifying join points with generics with @AspectJ

[Alexander Kriegisch <Alexander@xxxxxxxxxxxxxx>]

"Invalid absolute type name" kind of says it all. Try java.util.ArrayList instead.

Hi guys,

I’m getting the message “no match for this type name: ArrayList
[Xlint:invalidAbsoluteTypeName]” at @Before declaration.

My aspect:

@Aspect
public class Model {
   @Pointcut("get(ArrayList<String> Component.a)")
   public void getList() {}
   @Before("getList()")
   public void starting(JoinPoint pjp) throws Throwable {
       System.out.println(pjp);
   }
}

My sample code

import java.util.ArrayList;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.*;
class Component {
   private ArrayList<String> a = new ArrayList<String>();
   public void m() {
       a.add("hellow");
       System.out.println(a);
   }
   public static void main(String[] a) {
       new Component().m();
   }
}

Applying withincode to m() method, AspectJ gives the following join points:

get(ArrayList Component.a)
call(boolean java.util.ArrayList.add(Object))
get(PrintStream java.lang.System.out)
get(ArrayList Component.a)
call(void java.io.PrintStream.println(Object))
[hellow]

Note that the join point for ArrayList is identified without generics. But,
if I write

@Pointcut("get(ArrayList Component.a)")

AspectJ shows the same message. How can I intercept the ArrayList?

Best regards
