new version of A:
class A {
public static void main(String []argv) {
A a = new A();
System.out.println(a.f);
a.f=100;
System.out.println(a.f);
}
}
ajc -1.5 A.java X.java
java A
42
100
What makes this work is that the ITD is PUBLIC (public int A.f = 42).
You have to be compiling the system using ajc and not javac.

Hi,
I think it is not possible to do the following with AspectJ but
maybe I am wrong :
1) I have a java class A which has no fields.
2) I use an aspect to introduce a field called f into A.
3) I can use f in A as if f were hard coded (in the java source)
into A.
Is this possible ?
I know it is possible to something similar by providing default
implementations
for interfaces but that is not my question (interfaces can only
have final fields).
Cheers,
Jozsef
