Re: [aspectj-users] Can we access any static join point information in

[Andy Clement <andrew.clement@xxxxxxxxx>]

Declare warning and error are matched during compilation.  This means
it would be a little awkward to run any code being compiled as part of
producing the message.  However, with appropriate definition of
inserts, we are basically talking about the same feature:

%DT% - declaring type name
%N% - name

declare warning: call(* Hello.*(..)): "Illegal call to %DT%.%N%(..)";
