Thanks Matt,
I know that much of the annotation-style thing is working, because I am
actively using it already. However, what is lacking is the ability to
have an advice applied iff a condition is true for the attributes of an
annotation. Consider the following
@MyAnnotation(foo = true)
class X {
}
@MyAnnotation(foo = false)
class Y {
}
It would be very nice to be able to define pointcuts that select the
first but not the second. Hope this clarifies what I mean?!
Regards,
Sven

Yes, this is possible by exposing the annotation context at runtime, so
long as your annotation has runtime retention, as mentioned in the
developer's notebook.
For example, say classes X and Y both have a bar() method, but you only
wanted to match the one in X, you could do something like:
before(MyAnnotation anno) : execution(* bar(..))
&& @within(anno) && if(anno.foo()) {
}
Note that in AJDT the markers and cross references view etc will show a
(potential) advises relationships for both X and Y, but the advice arrow
will be one with a question mark, which indicates that a runtime test is
going to be applied to determine that exact matches.

Matt.

Hi Barry,
Yes, the latest AJDT dev builds (both 1.2.1 and 1.3.0) contain AspectJ 5
M3a.
We plan to update the version of AspectJ contained in AJDT more
frequently, and when we do this we'll post here, and update the AJDT New
Features page (and post to the AJDT home page, which now offers an RSS
feed).
Regards,
Matt.
