Re: [aspectj-users] Matching based on extension type
|
Hi Andy.
That's what I thought, then. It is not possible statically! :-(
Dynamically, I knew we could do it.
Thanks for your quick reply, as usual :-)
Do you think this behaviour will be added in a future version of AspectJ?
Regards,
Paulo Zenida
Citando Andy Clement <andrew.clement@xxxxxxxxx>:
not statically, but dynamically:
before(): staticinitialization(*Base) {
if
(thisJoinPointStaticPart.getSignature().getDeclaringType().getSuperclass().getName().endsWith("Base"))
{
throw new
IllegalStateException(thisJoinPointStaticPart.getSignature().getDeclaringType().getName()+"
extends
"+thisJoinPointStaticPart.getSignature().getDeclaringType().getSuperclass().getName());
}
}

Hello all.
Is it possible to do AspectJ matching based on the extension clause defined
in a given type? For instance, can I define a policy in which it is not
possible for a class whose name ends with Base extend another class whose
name also ends with Base?
Something like (simplified syntax):
declare warning : *Base extends *Base : "You should not extend a Base class
from another Base class";
I looked for it in the Web and tried several approaches but no good
results, unfortunately... :-(
Thank you for your attention.
Kind regards,
Paulo Zenida
