[aspectj-users] UML for AspectJ
|
Hi everyone,
I've talked to a couple of people about this because this is one area
where my company is keen to see proof that aspects can indeed be
modeled.
One of the suggested mechanisms is to look carefully at Use Cases, in
particular towards their realizations. Admittedly the logical model
calls for some new stereotypes and a perspective change on the
developers part but in effect aspects can be modeled as forms of
classes within this context. It's at the Use Case realization level
that the distinction can be made between a cross-cutting approach or a
more traditional OO solution. Admittedly I haven't found anything
formal to this effect but this is what has seemed to work reasonably
well for me.
Does anyone else out there have anything more formal? I do use the AJDT
browser too but that is not much use when you are in the early days of
design development and no actual code is in existence so UML still
seems to fit the bill at that point.
Just my two pence :)

Hello, I am very new to AspectJ and AOP in general. I am
wondering if there is any sort of UML specification for AOP.
Specifically, can an AO design fit with a normal OO class
design? My understanding of AOP is that an aspect is
actually a class(or maybe that a class can hold multiple aspects).
Any ideas?
Usually UML does not fit quite well because aspects are designed to
_crosscut_ thorugh classes. You could see them as some kind of filter
lying
over your whole class hierarchy. Thus UML does not fit very well I'd
say.
The only useful visualization I know is the one provided by the Aspect
Browser or AJDT tools respectively.
HTH,
Eric
