Hi Andy,
Thanks for answering! That's good see the support for the classical
syntax... but the @annotation style need to be updated... I'm not talking
about if pointcuts. See bellow:
public interface I {
@Pointcut("execution( * *(..))")
public static void pc(){}
}
We both know that interfaces now support static methods and we also know
that the above pointcut (which does not include an if pointcut) is valid if
declared within a class, but it's forbidden within an interface... the
compiler says the following:
"pointcuts can only be declared in a class or an aspect"
cheers
