Re: [aspectj-users] PointCut problem

["Wes Isberg" <wes@xxxxxxxxxxxxxx>]

Hi -

Classes are always initialized within the scope of the class
(see staticinitialization(T)).

To limit constructor calls, try something like

  declare error: !within(Y) && call(packageK..*.new(..)) : 
      "Y is factory for all packageK";

I'm not sure there's a *general* way to permit any class to call
its own constructor (e.g., in its own static methods). For a 
specific class, you can say

  declare error: !within(Y) && !within(SomeClass) && 
      call(SomeClass.new(..)) : "Y is factory for all packageK";

Remember that this() and super() calls are not join points, so
this code would not trigger any declare-error:

   SomeClass() { this("default"); }
   SomeClass(String s) { this.name = s; }

So you might not need to permit a class to call its own 
constructor. 

Hope this helps -
Wes

Subject: [aspectj-users] PointCut problem
Hello

I'm trying to create an aspect that gives an compiler error when this doesn't occur:

- all the classes inside the package K can only be initialized inside a especific class Y or inside the scope of the especific class.


I created this one that gives the error but permits the initialization of any class that is inside the package K be done by any other of that same package
    pointcut ActionsInstancesCreation() : !within(packageK..*) && !within(Class Y) && initialization(packageK..new(..));

Can i do a pointcut to resolve my error?
