Re: [aspectj-users] intercept Class but not SubClass

This defines a marker interface, we will use it to make sure that any subclass of MyClass implements this interfce but MyClass does NOT.

This declaration makes a set of types implement SubclassOfMyClass. MyClass+ means MyClass or any of its subtypes. !MyClass means to exclude MyClass. So MyClass+ && !MyClass matches any subclass of MyClass, but NOT MyClass itself.
For more details on declare parents and type patterns, I'd get a good book on AspectJ (like AspectJ in Action), or look at the AspectJ programmer's guide.
