Hi,
i want to make inter-type declarations which do not refer to a concrete type.
Hence i am using a generic aspect which has a generic type parameter. For
inter-type declarations i need to define an interface which will be the target
for the inter-type declarations and which the generic type implements. It is
just like descibed in the section Generic Aspect here:
http://www.eclipse.org/aspectj/doc/next/adk15notebook/generics-inAspectJ5.html
Here is the aspect:
public abstract aspect GenericAspect<Type extends ConstrainingClass> {
interface HelperInterface {
void someMethod();
}
declare parents: Type implements HelperInterface;
public void HelperInterface.someMethod() {
this.someConstrainingClassMethod();
}
}
As you can see, i want to call ConstrainingClass.someConstrainingClassMethod()
which is declared on ConstrainingClass, but this is not possible since
HelperInterface does not know about the methods of ConstrainingClass. Maybe i
could extend the interface with the interface of ConstrainingClass but the
problem is that this class does not implement any interface (its from some
foreign library).
Is it possible somehow? In the end i want to have an aspect that can be applied
(by binding its generic parameter) to arbitrary classes extending
ConstrainingClass while using methods of ConstrainingClass.
Best regards
garz
