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

[saadbin abid <saad.softwareengineer@xxxxxxxxx>]

Hello Andrew and Aspectj community,
Thank you very much for the reply. well let me try to explain the problem again. First of all the classes and aspects are there in the project. all i need to do is to read the aspects (.aj files) to find out what java classes or aspects are affected by any particular aspect

 for example
In the earlier example i mentioned I have A.java and B.java. I made an aspect C.aj,which actually checks that if both A.java and B.java are running than modify A.java  or B.java so that both can actually run together. So I actually want to know which Java class function (A.java and B.java) is extended by C.aj

Iets say I have aspect implements "requiredActivation" dependency between  part

@activation dependency
 * When Hex is selected, the logical operators can be active

"privileged aspect HexPanel_LogicalOp {
    before(HexPanel panel) :
        execution(* setButtons()) && this(panel) {
        panel.buttons.elementAt(4).setPObject(new And());
        panel.buttons.elementAt(9).setPObject(new Or());
        panel.buttons.elementAt(14).setPObject(new Xor());
    }
}
"  
The above mention aspect code is that this aspect advises HexPanel.setbuttons. I want to know this information "This aspect requires HexPanel so that logical operations can be activated". This aspect calls HexPanel and add some functionality to it (add buttons) so that logical operation can be performed.

I hope i make you understand. All i want to traverse aspects present in the AspectJ project and find out calls to other .aj or .java files.

How can i proceed with it?

Best regards
 
 Saad

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.
