Re: [aspectj-users] Accessing protected methods of parent class from wit

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi Sina,

That should work, the use of 'privileged' should cause generation of
an accessor method that can then be used by the aspect.

here is my sample:

==== 8< ==== Parent.java
package com.somewhereelse;

public class Parent {

	protected void foo() {
		System.out.println("foo!");
	}
}
===== 8< ====
===== 8< ==== Child.java
package com;

import com.somewhereelse.Parent;

public class Child extends Parent {

	public static void main(String[] args) {
		new Child().m();
	}
	
	public void m() {
		
	}
}
===== 8< ==== Overthere.aj
package xxx;
import com.Child;

privileged aspect Overthere {

	before(Child c): execution(* Child.m(..)) && this(c) {
		c.foo();
	}
}
===== 8< ====

> ajc -1.5 com/Child.java com/somewhereelse/Parent.java xxx/Overthere.aj -showWeaveInfo -d output

Join point 'method-execution(void com.Child.m())' in Type 'com.Child'
(Child.java:11) advised by before advice from 'xxx.Overthere'
(Overthere.aj:6)
	
> cd output
> java com.Child
foo!

Here is the accessor in the Parent class:

> javap com.somewhereelse.Parent
Compiled from "Parent.java"
public class com.somewhereelse.Parent extends java.lang.Object{
    public com.somewhereelse.Parent();
    protected void foo();
    public void ajc$privMethod$xxx_Overthere$com_somewhereelse_Parent$foo();
}

So what is different about your configuration from mine?

cheers,
Andy
