[aspectj-users] how to capture a newly initialized object in a call poin

["Henry Canterburry" <canterburry@xxxxxxxxx>]

I am pretty new at this aspect stuff and have been reading one of the
Eclipse AspectJ Books. One of the passages concerning initializer
pointcuts states:

"When the method signature of a call
 _expression_ specifies a constructor, this  will provide the instance (if the call is being made from a nonstatic context) of the object making the constructor call. 
target

is always unbound—this means attempts to use it to match on a type or
expose the target of the call will leave you with a pointcut that does
not match the constructor call."

So,
is it then at all possible to write a pointcut that both captures the
instance of the calling object and the instance of the object just
created?

i.e 

What I really want to write is this:

    pointcut newEventSource(ModelChangeEventSource
 source, ModelChangeEventSource listener) :



        call(ModelChangeEventSource+.new(..)) &&
        this(listener+) &&
        target(source+) &&



        within(*.core.model.*);
        



    after (OntoModelChangeEventSource source, OntoModelChangeEventSource listener) returning : 



        newEventSource(source, listener)



    {
        source.addModelChangeListener(new ChangeListener
(listener));
    }

This
basically says (or at least should say) if any event source
instantiates any new event source, then add the first source as a
listener to the newly created source.

This is for purposes of event propagation between event sources inside a domain model.
