Re: [aspectj-users] loading and traversing aspects (.aj files)

[Andrew Eisenberg <andrew@xxxxxxxxxxxx>]

I think I understand what you are trying to do.  You would like to
walk the parse tree to see what other files are referenced.
Unfortunately, the part of the AjAST hierarchy that you require has
not been completely implemented (look at
org.aspectj.org.eclipse.jdt.core.dom.PointcutDesignator and its
subclass DefaultPointcut).  So, the information that you require is
not really available from the AjAST.

I think your best bet is to use a
org.aspectj.org.eclipse.jdt.internal.compiler.parser.Parser object and
do the parsing yourself.  If you need some pointers on how to do this,
I can provide it.
