Just as a concrete class at the bottom of a hierarchy must implement any
inherited abstract methods, so a concrete aspect must provide a definition
('concretize') any abstract pointcuts it inherits, otherwise it is still an
abstract aspect.
abstract aspect Foo {
abstract pointcut scope();
before(): execution(* *(..)) && scope() {
System.out.println("Entering >"+thisJoinPoint);
}
}
aspect Goo extends Foo {
// must provide a definition of scope()
pointcut scope(): within(com.mypackages..*);
}
