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

[Andrew Eisenberg <andrew@xxxxxxxxxxxx>]

I am not exactly sure what you are trying to do.

I think you are saying that you want to do some code generation in
C.aj based on the state of your A.java and B.java files.

If this is the case, then you do not need to create your own builder,
but rather you need to implement and register an
IResourceChangeListener object with the workspace.  This listener will
be notified whenever a workspace resource is changed.  You should look
at the eclipse documentation for more information on this.

As for the code generation, yes, you may need to use the AjAST for
this.  It is similar to the JDT DOM api, so have a look at that.

I may have misinterpreted what you are trying to do, so please explain
more precisely and I can give a more detailed answer.
