Re: [Springframework-developer] Method Interception By Name

[Rod J. <rod...@in...>]

I know doco is lacking in this area. I'm gradually adding to the AOP docs,
although due to time constraints, only at the rate of about half an hour a
day until the end of the month, when I should have time to finish it off
properly.

Which class names do you consider hideous? I'm wondering whether it's
AOP-speak hideousness or Spring hideousness. It might be possible to address
the latter category of hideousness (although we want to keep changes to a
minimum until 1.0 final).

Regards,
Rod
