[aspectj-users] Use null for args in pointcut

["Conway. Fintan (IT Solutions)" <Fintan.Conway@xxxxxx>]

Title: Message

Hi *,

 

I have a problem where I have to extend a pointcut in a super aspect.  The signature of this pointcut is as follows :

protected abstract pointcut subjectChange(Subject s, Object args); 

One of the aspects which extends this super aspect does not require the 'args'  parameter.

My overriding pointcut looks like :

protected pointcut subjectChange(Subject subj, Object arg) :

(

call(* Pot.add(..))

||

call(* Pot.refresh())

)

&& !within(PotObserverUtilTest)

&& target(subj)

&& args(arg); 

This pointcut matches the Pot.add method, since it does have an argument.  However the Pot.refresh() method is not advised since it does not have any arguments.  I have to override the abstract pointcut.

Is there any way to get the Pot.refresh() advised in this scenario?  (args = null?)

Any advice gratefully appreciated,

Fintan
