invokingMethods broken in moose or inFamix - Moose-dev

4 Dec 2011

      hi guys,
one of my students encountered a case where
FAMIXMethod#invokingMethods is not correctly set. i wonder whether
that is a moose problem or an infamix one. anybody knows about this?
the original message is at the end of this mail.
thanks,

I assumed that FAMIXMethod >> invokingMethods would return all methods
that invoke the method represented by the FAMIXMethod instance, this
doesn't seem to be the case.

I created an mse file with inFamix from the code in svn at
http://svn.apache.org/repos/asf/incubator/stanbol/trunk/enhancer/engines/key...

The class org.apache.stanbol.enhancer.engines.keywordextraction.linking.EntityLinker
has both private methods with an empty collection of invokingMethod as
well as with a non-empty one:

- The method getLinkedEntityTypes has an empty collection of invokingMethods

even though the method is in fact invoked:

public void process(){
...
if(linkedEntity == null){
linkedEntity = new LinkedEntity(selectedText,
suggestions, getLinkedEntityTypes(suggestions.subList(0, 1)));
linkedEntities.put(selectedText, linkedEntity);
}

By contrast in the same class

- porcessRedirects has {process} as collection of invokingMethods,
where processRedirects is invokes as follows:

public void process(){
...
if(config.getRedirectProcessingMode() != RedirectProcessingMode.IGNORE){
for(Suggestion suggestion : suggestions){
processRedirects(suggestion);
}
}

All the method I've looked at with an empty collection of
inkingMethods in fact had at least one invokation, I tried to make a
famix model for just the class EntityLinker as this class has both
private method with empty as well as with a non-empty set of ivokers
according to Moose, I hoped that with a small mse file it would be
easier to analyze the problem.

Unfortunately I didn't manage to create such an mse model, I'm getting
the following exception message running `inFamix -lang java -path
source -mse test.mse`:

Unfortunately as inFamix is not open source and because of section 2.3
of the SLA it's hard for me to tackle this problem so I would
appreciate some help.
