I agree that this kind of prototyping
support should be the job of a tool, and not of special language support.
We had a prototype “join point probe” tool in pre-AJDT IDE support.
It would let you put in a pointcut, then show you the matches in a tree. But
we never quite worked out the UI (e.g. matches showed in new view, you had to
fully qualify type names). Julie Waterhouse and I spent a bit more time discussing
how this could work for AJDT, and thought a good way of doing it would be to
allow you to create a .ajpage (similar to a .jpage file), then select any
pointcut, right-click, and hit “show matches” to temporarily show
everything the probe matched in the Cross References view (the content would
stick if the view were not in “link with editor mode”).
Since for the first time three is user
demand for such a tool I have created a report for it. If you have suggestions
for how you would like it to work please post them here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=109759
Cheers,
Mik

Yes,
I can get join points in AJDT visually.
But it is very handy to print a list of join points in console or a text
file when one have to find problems with aspects.

RE: [aspectj-users] AOP tools
Don't you in effect get this from AJDT? Unless your project
weaves into external JAR's, you get immediate feedback from AJDT of what Join
points are affecting which classes.

Hi All,
I
like the idea to have a tool probe join points take place in java packages. It
can be a new tool or an option in ajc -- aspectj compiler. Does the compiler
has such option already, I did not pay attention on its new move recently.
Thanks
All,
Bo

If I'm understanding Mohan correctly, I
think he just means a sort of
interactive pointcut matcher, so you could type in
a pointcut and you'd
see what matches you get on your inpath, something
like this:
C:\>ajsh -inpath myjar1.jar;adir\others.jar
ajsh> call(fi.mypackage.*.*(..)) &&
!within(fi.mypackage.*);
fi.otherpackage.SomeClass:57 : method-call(double
fi.mypackage.AClass.doSomething(int) : double d =
anObjectFromThatPackage.doSomething(1);
fi.otherpackage.SomeClass:112 : method-call(void
fi.mypackage.XClass.save(int) : x.save();
...
No weaving is necessary.
That would be quite a handy tool. = )
BTW, would something similar be usable in
AJDT, i.e. you could click
on a pointcut and see a sort of "wincvs
annotation" style list of
matches, like above (with the actual code that
matches shown)? The texts
would naturally act as hyperlinks to the actual
code, and different
matches could have different background color to
make it easy to tell
them apart. The columns could be turned on/off,
e.g. if you do not wish
to see what joinpoint matched but just the source
code or vice versa. I
think this would complement the present Cross
References view nicely (or
maybe this functionality could be added to that
view?).
Sounds cool to me, what do you others think?
