Hi Rajat,
whie it may sound confusing the first time, you can use "Object around(...)"
also to weave around void methods. For example :
Object around() : execution(.. something matching methods here ...) {
System.out.println("Doing something");
return proceed();
}
AspectJ will know that the method it is weaving is a void method, and return
a special value that represents "void".
If you use "return proceed(input)" in the second advice in your example, it
will apply to both cases.
Hope this helps,
Simone
