Re: [aspectj-users] Don't pass go --> AspectJ Idioms for Aspect-Oriented Software Construction
|
Hugh,
I suspect that many introductory articles on AOP you have found on-line
have not been much satisfactory or convincing. The problem that the AOP
potential is easily misused and misunderstood (hence, most developers -
including me some time ago - hardly see something useful beyond
simplistic development aspects such as logging). I believe that the
following article reveals some idioms on how to achieve most of the AOP
potential.
AspectJ Idioms for Aspect-Oriented Software Construction
"The way how aspect-oriented features are applied has a direct impact on
how reusable aspects are and how easy they can be applied to other
object-oriented programs. Hence, the application of aspect-oriented
language features must follow deliberate design decisions and cannot be
used ad-hoc."
http://dawis.informatik.uni-essen.de/site/site/publications/papers/aop/2003_HSU_AspectJIdioms_EuroPLOP_2003.pdf
Also for real-world samples on how to apply most GoF design patters,
explore this wonderful research project.
Design Pattern Implementation in Java and AspectJ

Indeed, its distribution has 2 implementations: in pure Java and
AspectJ. You can then compare them to make solid arguments of adopting
AOP. For instance, see the Observer Protocol for a head start! You'll be
amazed, trust me!
Caveat: these implementations are still based on pre-Java 5, so they
could be modified to include Java 5 and AspectJ 5 features though.
A note to AOP folks, do you also have similar resources Hugh, me, and
others should know about too?
Hope this helps,
Dmitri

I came accros aspectj and aop when researching an inhouse problem
several months
ago. I tried to use aspects for the project but it only solved part of
my problem so I had to
abandon it for something else. But I did realise that there is great
potential in
the use of aspects. However am having a hard sell with it as other
developers
in the company only see it being used for logging. Are there any
articles , examples
experts I could refernce to give more weight to my argument of adopting
aop going
forward
