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

[ujuarez]

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
