Re: [aspectj-users] intercept Class but not SubClass

[Eric Tanter <etanter@xxxxxx>]

Thanks Ron.

Actually, it is understandable as a solution, but maybe not the way 
users want to think about it.

The whole "trick" is needed because (as I understand it), in declare 
parents:
- MyClass means "MyClass only"
- MyClass+ means "MyClass + subtypes"

and in the this PCD:
- MyClass means "MyClass + subtypes".

Isn't this a semantic mismatch?
There is no direct means in the this PCD to refer to "MyClass only".

Ideally, for avoiding confusion for users, both ways should be similar, 
independently of whether they are doing an inter-type declaration or 
specifying a type pattern in a PCD.
But if the idea is not to change the current semantics of the type 
pattern within the this PCD (so that a change does not break old code), 
then a possibility would be to add a way to say "and not its 
subclasses", something like:

pointcut baseConstruction() :
  execution(MyClass.new()) && !this(MyClass-);

And then you don't need to be adding a marker interface and all.

?
