RE: [aspectj-users] AOP tools

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,

 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 =
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?
