[aosd-discuss] Java project to AspectJ

[Marius Marin]

Hi,

AJHotDraw is a "by hand" refactoring of a number of
concerns identified in JHotDraw. Although I haven't
used elaborate refactorings, Dave's observation is
valid --  imo, this is mainly because there is not
much done on general solutions (i.e., kind  of pattern
refactoring-solutions) for “common” crosscutting
concerns. As a matter of fact, there is very little
about a categorization of such common crosscutting
concerns, which, in my opinion, would be very useful
for both mining these concerns and consistently
refactoring them.

Here you can find some more mining results for
JHotDraw - this list uses a categorization of common
concerns to describe the results:

.

And more aspect mining results for several popular
applications - the categorization is less thorough:

. 

cheers,
Marius
