Re: [aspectj-users] Re: Aspect and Exception Handle

["Arjun Singh" <aasingh@xxxxxxxxx>]

Hi,

If you have a situation like this:

class Foo {
   public void boo() {
       try {
           ...
       }
       catch(Exception e) {
           ...
       }
   }
}

and you would like to advise the handler, you could have an advice
that is something like the following:

before(Foo foo, Exception e): handler(Exception) && within(Foo)
       && args(e) && this(foo) {
   ...
}

You would then have access to the class via the foo object.  Is this
what you are looking for?  Or did you want to completely remove the
try/catch block via an aspect?
