Re: RES: [aspectj-users] thisJoinPointStaticPart & warning

Andre,

You might like to pick up a copy of Eclipse AspectJ
(http://www.awprofessional.com/title/0321245873) and read Chapter 11. Here
is an extract showing the SystemArchitecture aspect which describes the
structure of the Simple Insurance application:

public aspect SystemArchitecture {

      public pointcut uiCall() :
            call(* insurance.ui..*(..)) ||
            call(insurance.ui..new(..));

      public pointcut modelCall() :
            (call(* insurance.model..*(..)) ||
            call(insurance.model..new(..)))
            && !javaLangObjectCall();

      public pointcut modelImplCall() :
            call(* insurance.model.impl..*(..)) ||
            call(insurance.model.impl..new(..));

      ...

      public pointcut inUI() : within(insurance.ui.*);
      public pointcut inModel() : within(insurance.model.*);
      public pointcut inModelImpl() : within(insurance.model.impl.*);

      ...
}

And the PermittedComponentInteractions aspect which polices dependencies
between them:

public aspect PermittedComponentInteractions {

      declare warning : SystemArchitecture.uiCall() &&
                  !SystemArchitecture.inUI()
            : "No calls into the user interface";

      declare warning : SystemArchitecture.modelImplCall() &&
                  !SystemArchitecture.inModelImpl()
            : "Please use interfaces in insurance.model instead";
      ...
}

Enjoy!

Wes,

 I'm trying to check dependences between classes:

 pointcut pc() : call(* *.*(..)) && !call(* MyClass.*(..)) ;

 before() : pc() {
   String callerType =
 thisJoinPointStaticPart.getSourceLocation().getWithinType().getName();
   System.out.println("MyClass depends on '" + callerType);
 }

 I would like to inform dependences statically, using declare warning...

 André

 Would you make a case why it should and how it could?

 Hi,

 Why it's not possible to use thisJoinPointStaticPart in "declare warning"
 ?

 Thanks,

 André
