AroundAdvice is invoked instead of a join point. The special thing about the
around advice is that it can nevertheless proceed the join point if it likes to and
can also change the arguments to use for the procession and alter the return type if
wished. This means with the around advice you can change contextual information of
the join point it is woven into.
public function execute(joinPoint:JoinPoint, args:Array)
Executes the actions to perform instead of the given joinPoint. If the
joinPoint shall nevertheless be executed this has to be done manually
by invoking the JoinPoint.proceed method.
The implementation of this method decides whether the actual join point is bypassed or if it is executed. It can also be decided what arguments to use for the procession and what to do with the response of the procession be it a return value or an exception. This means you can alter the context as you please.
If you use the proxy returned by the AbstractAroundAdvice#getProxy method to overwrite the actual join point, this method is executed instead of the join point and the result of this method is returned to the invoker of the join point.
