Re: [aspectj-dev] State of AjAST
|
As Matt says - the AJ ast support is not all there .. we only put the
very basic shape in and as users need it, they/we can add more. We
have some contributions from another user that should go in soon to
extend it for a system they were building. Issues relating to it can
be discussed under the bug you found (110465) - that's where to post
what you've found or patches that extend its functionality...

Hi Simon,
The current AST support is not fully formed, but you should be able to
get further by creating a PointcutDeclaration instead of a
DefaultPointcut. This is because a DefaultPointcut is a type of
PointcutDesignator, which cannot be added directly to a
BodyDeclaration.
Regards,
Matt.
