And I just discovered another thing.
FAMIXInclude overrides #from and #to, and when doing so, they also change the type of the
property.
FAMIXInclude>>from
<MSEProperty: #from type: #FAMIXFile opposite: #includingFiles>
^ from
FAMIXAssociation>>from
<MSEProperty: #from type: #FAMIXNamedEntity> <derived>
^ self subclassResponsibility
The property is marked as <derived> in the superclass, and this means that the value
should come from somewhere else. Essentially, #from and #to are just polymorphic
properties, and are not meant to store the concrete value.
I now changed the code to have:
- FAMIXInclude not depend on from/to properties, but instead on new source/target ones.
- introduced incomingIncludeRelations/outgoingIncludeRelations in FAMIXCFile.
In the process, I also found that other places completely messed up the from/to
definitions:
FAMIXInvocation>>from
<MSEProperty: #sender type: #FAMIXBehaviouralEntity opposite:
#outgoingInvocations>
<MSEComment: 'Behavioural entity making the call. from-side of the
association'>
^ self sender
One clear point here is that we need more constraints and tools to guide newcomers. I will
follow up on that.
Cheers,
Doru

Hi,
I went quickly through the changes from the FAMIX-C package. The Multivalue code looks
good.
Here are two remarks:
1. I am not convinced about having CompilationUnit and Header be subclasses of CFile
(which is a subclass of File). But, to make an opinion I would first like to see a model.
@Alex, could you provide a simple MSE model to play with?
2. I would want to change is the names of the following two properties:
FAMIXCFile>>includedInFiles
<MSEProperty: #includedInFiles type: #FAMIXInclude opposite: #includesFiles>
<multivalued> <derived>
<MSEComment: 'includedInFiles relationships, i.e. files that includes this
file.'>
^ includedInFiles
FAMIXCFile>>includesFiles
<MSEProperty: #includesFiles type: #FAMIXInclude opposite: #includedInFiles>
<multivalued> <derived>
<MSEComment: 'includesFiles relationships, i.e. files included by this
file.'>
^ includingFiles
The names suggest that the result will be a collection of File objects, but it is
actually a collection of Includes.
It is a bit tricky to name these selectors, but we could use the same convention we used
for invocations, and we could have:
- includedInFiles ==> incomingIncludeRelations
- includesFiles ==> outgoingIncludeRelations
What do you think?
Cheers,
Doru
