MooseModel of Smalltalk code

Hi,

I am working on MooseModels of Smalltalk code. There are some things that I feel strange:
- there are some FAMIXAnnotationTypes and thus also FAMIXAnnotationTypeAttribute in Smalltalk. The comments of these classes refer to Java and never to ST. It seems corresponding to pragma such as: <expected failure>.

Take a look at the diagram from here:

http://www.themoosebook.org/book/internals/famix/core/annotations

smalltalkMethodAnnotated

  <primitive: 'primAnyBitFromTo' module:'LargeIntegers'>

the method has one AnnotationInstance that is of AnnotationType <primitive:module:>. The AnnotationType has two AnnotationTypeAttributes that have no name in the case of Smalltalk. The AnnotationInstance has two associated AnnotationInstanceAttributes with 'primAnyBitFromTo' and 'LargeIntegers'.

 

- the FAMIXGlobalVariables have their belongsTo equals to nil. Only the declaredType is defined.

Yes. Is this an issue?

 

- some FAMIXInvocations have no receiver. It seems that when a method m1 refers to a method m2 that does not belong to the model, the receiver is considered as nil. In Java, due to the statically typed character, we would have had a stub corresponding to m2. But in ST, because of the dynamically typed character, the receiver is nil. It means that before performing actions on Invocations, we have to ensure that they have receiver. Are we aware of that? Do we agree with that?

No. The receiver refers to the variable that receives the message. Consider something like:

self foo bar

"self" is the receiver of "foo", but the receiver of "bar" is "self foo". In the second case, the receiver will be marked as nil.

Cheers,

If I can get you feedback on that points, it would be great.
Thanks in advance.

Anne
