Re: [aspectj-users] writing around advice for an unknown method

[Ashank <k_arvind_shankar@xxxxxxxxx>]

Thank you Jean Louis, Mathew and Hemal for your answers.

Hemal, I just want to add that, apparently, one can write code like

Object result = proceed();
<code to execute after proceed>
return result;

and it would still work for methods that return void. That is what I
gathered from a brief test.
