[aspectj-users] Argument selector survey

[ajUnit <ajunit.contact@xxxxxxxxxxxxxx>]

Hello,

I'm developing a unit testing extension for AspectJ, called ajUnit
(https://github.com/loddar/ajunit).

Currently I stuck with arguments selector. The argument selector in
aspectj is quiete powerful, but I guess not everthing is used in practise.

For example "/execution(* *(*,..,int,*,boolean,..*))/" is valid argument
selector, but what's the use case?!

So here come my questions: Which kind of argument selector have you been
used or you think there is a real use case for it?

Some common examples:

  * execution(* *(.., int))   last argument is an int
  * execution(* *(int,..)) first argument is an int
  * execution(* *(.., MyClass,..))  at least one argument is of type MyClass
  * execution(* *(*)) has exactly one argument
  * execution(* *()) has no arguments
  * execution(* *(..)) has any number of arguments

I'm not interested what kind of selection could be done to a single
argument. The more I'm interested which combination of .., * and
argument selector is of real use out there. If you have a uncommon case,
it would be nice if you explain it.

Thx Marko
