Title: RE: [aspectj-users] Problem with declare parents

You have a class A extending an aspect B - this is not allowed by AspectJ.
Only an aspect can extend another aspect.

Subject: [aspectj-users] Problem with declare parents

Hi

I have two aspects B and C and a object A

public class A {
       
        public A()
        {              
        }
       
        public void doNothing()
        {              
        }

}
public aspect B {
       
        public void sayHello()
        {
                System.out.println("Hello World");
        }

}

public aspect C {

        public interface D {

                public void sayHello();
               
        }

        declare parents : B implements D;      
        declare parents : A extends B;
}

This leads to a compiler error stating:
Implicit super constructor B() is not visible for default constructor. Must define an explicit constructor

What is wrong since A does not see B
