[aspectj-users] One target for intertype declarations

[David Pearce <david.pearce@xxxxxxxxxxxxx>]

Hi all,

I would just like to confirm something regarding the elimination of 
"multi-intertype declarations".  Basically, I want to add a field to 
every object instance.  So, perviously, I could have just used something 
like:

aspect A {
        public int *.theField = 0;
}

But, since AspectJ 1.1 this syntax is no more.  So, now my question.  Is 
the pertarget specifier supposed to be used instead of the above now?  I 
realise that the README-11.html indicates pertype should be used for 
static field member introduction (if it existed, that is), so I figure 
the reasoning is the same.

Also, how is pertarget actually implemented?  Does it involve some kind 
of hashmap lookup or not?  If not, then what?

Any help would be appreciated!
