RE: [aspectj-users] Introduction on more than just one class

[Jim.Hugunin@xxxxxxxx]

The method suggested below will work in AspectJ-1.0, but is not permitted in AspectJ-1.1.  In order to enable truly modular compilation of aspects AspectJ-1.1 doesn't permit performing introduction on a type pattern.  The 1.1 answer is to use an interface combined with declare parents, i.e.

aspect A {
    interface Bar { }
    public void Bar.bar() {
        System.out.println("An introduced method");
    }
    declare parents: Foo* implements Bar;
}

This is explained in slightly more detail in the changes file for 1.1,
