[aspectc-user] Element counter example -- getting compile error

[siva chelliah]

It would be nice if you can post some working example coded on the web. I
have modified the code completely to use proper .h and .cpp files. 

I am getting some errors, but I will fix them and post the final code to
this list shortly.

During the test, I have found an error in the tutorial:

In the ErrorAspect.ah file, you have the following line:

advice execution("% Queue::dequeue(...)") && result(item)
...
But dequeue has no arguments! So I think it should be:

advice execution("% Queue::dequeue()") && result(item)
...

Instead testing the item after the execution, another idea is to test the
variable 'first' to see it that is 0. Here is the advice for that:

advice execution("% Queue::dequeue()") && that(q):
  before(Queue* q) {
    if (q->first == 0) {
      throw QueueEmptyError();
    }
  }

What do you think about this?

A conclusion is simply the place where someone got tired of thinking
