Re: [aspectj-dev] State of AjAST

["Matt Chapman" <mpchapman@xxxxxxxxx>]

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.
