MSE file for FAMIX3?
by Simon Denier 29 Sep '08

29 Sep '08

Hi all I'm looking for the mse file describing FAMIX3.0 - I couldnt find it on the moose website. We want to load it with Fame VW and Fame for Java. Did anyone try that already? -- Simon Denier, PhD Postdoc, Ptidej Team DIRO, Université de Montréal

About stub creation
by stéphane ducasse 27 Sep '08

27 Sep '08

Hi I'm working on making shared variable available in sqmoose and I got the following situation When I import referenceModel When I reify TheRoot (from referenceModel) the importer create all the superclass up to protoobject and more..... Object class, .... Behavior... Just because it is importing recursively all the superclass chain. For my point of view this is wrong. I'm quite sure that the old importer did not go all the way up. It was creating the superclass as a stub and stopped there. I'm checking in VWoose to see what is the behavior but I propose to fix it too if this is not a squeakish behavior of the importer. What do you think? Stef

If you browse senders with VW you get them. And RBCrawler gets them as well, but filters senders by the result of a flow analysis with method scope (by doing the same abstract interpretation as RoelTyper does, as I found out later when comparing the two tools). That is, three numbers with different precision for the same metric. Example of error range in number of classes and methods: Fame uses 4 anonymous subclasses of Fame.MetaDescription to instantiate primitive descriptions. FAMIX will not model them, but Object withAllSubclasses will list them. That is, two numbers for the same metric. i.e., even something as simple as the number of classes is more than one number and thus the correct number of classes is rather a range of possible numbers. In physics error ranges are given as N+/-Err, in software analysis they could be given by making clear what has been measured and what is missing. See examples above. Of course, whether the above errors matter or not will depend on your use case. For some use cases they might be no problem, for other use cases they are critical or at least annoying. Whether you care are not also depends on your distance from source code. Consider for example a class blueprint. In smalltalk most #new methods call an #initialize method that typically creates new objects of a different type by calling #new again. Moose will thus visualize the two methods as calling each other even though any developer can tell they do not! For a consultant doing an offline analysis at 10'000 feet altitude that might be good enough, but for the developer using the tool while working at ground level the visualization must be precise or they stop using it because its results are obviously false... and this is why RBCrawler takes the whole pain of running a flow analysis, because I was eating my own dogfood :) cheers, AA

Browse source code
by Alexandre Bergel 26 Sep '08

26 Sep '08

Dear List, When I am browsing a Java model, let's say ArgoUML, I cannot browse the source code of the model. Pressing 'Browsing source code' when right clicking on an entity seems ineffective. Is there a way to fix this? If no, I could work on this. Any hint where to start?

how in the script editor
by Stéphane Ducasse 25 Sep '08

25 Sep '08

can we get all the packages from a list of classes? Doru is there a way that the script does not just need a predicate and return a subset but can get a full block If I have a list of classes I would like to get a group with all the packages of the classes. So a kind of flatCollect on the result Stef
