Re: [aspectj-users] Basic Question on Aspects

[Nicholas Lesiecki <ndlesiecki@xxxxxxxxx>]

Peter,

Thanks for the excellent reply.

Sreekanth, For additional examples check:

http://dev.eclipse.org/viewcvs/indextech.cgi/~checkout~/aspectj-home/sample-
code.html?cvsroot=Technology_Project

Also, the two published books on the subject:
''AspectJ in  Action'' by R. Laddad
 http://www.amazon.com/exec/obidos/tg/detail/-/1930110936/
"Mastering AspectJ" by Nicholas Lesiecki http://tinyurl.com/66vf

Also, it's always a good policy to read the FAQ for a project. AspectJ's FAQ
is exceptional and contains enough information to answer this question.

Cheers,
Nick
