[Mondrian] Add a outer margin
by Mathieu Suen 25 May '07

25 May '07

Hi, I want to add a outer margin for a rectangle shape. So we can add space between 2 figures. What do you think about it? Do you have any hint for how to do it?

files and folders problem
by Adrian DOZSA 25 May '07

25 May '07

Hi, I have a mse file that contains only files and folders. It loads correctly into Moose but when i want to browse AllFiles or AllFolders it freezes and starts to eat a lot of memory (250MB and more) until i have to kill VisualWorks. Could you take a look and see what could be wrong with this model. Thanks.

Code Generator
by sellossa＠ensieta.fr 22 May '07

hi! I am still working on the code generator in Moose. With the BasicCodeGenerator class, you generate a metamodelling protocol for each attribute of a EMOF class What is the use of these "metamodel methods" ? thanks Sara

EMOF.Comment
by bouazzpi＠ensieta.fr 22 May '07

22 May '07

Hi, I'm dealing with comments in my importer. A comment can be defined in an element and not contain this element in its annotedElements. Do you think I should include by default the parent element in the annotedElements ? Futhermore, I have assimilated the Enumeration to an EMOF.Class and its litterals to property : but this is not really satisfactory. Do you want I implement Enumeration in the Meta-EMOF-Model according to the OMG spec ? Pierrick

I do not remember :) and in the ST extractor I reified all the namespaces (and forgot what is happening for the root). Stef

Re: Inheritance Definition - Again
by Tudor Girba 19 May '07

Hi, In general, a relationship requires your knowledge about both ends. If you have only half of the information, the model will be in an incomplete state, and analyses typically suppose the model is complete. But, in particular, you are asking if a class having no children shouldn't appear in Inheritance Relationships. Well, in this case, it is not that you do not know the other half of the information, but you certainly know there is no relationship. To state this, the simplest thing is to not have the relationship in the model :). Perhaps the confusion comes from not knowing what is required and what is not. But, the problem of required is only valid for properties of entities, not for entities. Thus, the properties "superclass" and "subclass" are required for an InheritanceDefinition, but we do not require an InheritanceDefinition for each Class. And please ask as many questions as you need, and do not be stressed about our time too much (at least not until we said so) :).

Hismo problems
by Richard Wettel 19 May '07

19 May '07

Hi, I am trying to see what it is possible to do with Hismo. After building a ModelHistory, I tried to inspect different entities here. The first problem that I bumped into is with NamespaceHistory. If I try to call allClassHistories on a NamespaceHistory instance, it tries to call #computeSubHistories:computedForEachVersionAs:withDescription:, which does not seem to be implemented anywhere. Any clues on how to make this work? The purpose of this is to be able to build package histories from namespace histories of Java systems (for instance, org.bla.foo namespace will produce three nested packages). I am working with the more-or-less-latest version of Moose, in VW7.5. Thanks, Ricky

Inheritance Definition - Again
by Muhammad Bhatti 19 May '07

19 May '07

Hi pipole, I would like to ask two novice questions. 1. What I understood from the earlier discussion: we do generate Inheritance definitions for framework classes/system classes that are referenced by user defined classes. My questions is that what does their inheritance definition look like. In the simplest case, the inheritance definition for a system class may look like this (my assumption: we discard the belongsTo attribute): FAMIX.Class { id: 121 name: 'FrameworkClass' stub: true } 2. What about the inheritance definition of user definied classes that do not have any children. How do we assign their subclass attribute. I have tried the following by putting stub: true (FAMIX.InheritanceDefinition (id: 18) (stub true) (subclass 0) (superclass 5) ) But it didn't work. I generate a file keeping the above defined hypotheses: minimal root definition and subclass=0 definition for classes having no children but the file fails to load in MOOSE. I am attached the file with this mail, just in case. The program defines a simple inheritance hierarchy with only one method. The inheritance hierarchy looks like this: shape <- rectangle,circle,trapezoid rectangle <- square,rectangle1 Circle <- Eclipse For this problem, I would greatly appreciate your help coz IMHO the documentation found on the Web provides several interpretations and can be a misleading. thanx in advance, Usman ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program. -- Ce message a ete verifie par MailScanner pour des virus ou des polluriels et rien de suspect n'a ete trouve.

Code Model with Variables
by Mircea Lungu 18 May '07

18 May '07

Hi, Doru introduced me to the SetUp package. I just thought I would share with you one of my favorite prerequisites from the Cincom store, one which I have just realized can't live without: RBCodeModelWithVariables - shows a panel with the instance variables for the current class Hope you find it useful, Mircea.

user questions
by Mircea Lungu 17 May '07

Hi moosers, This is not directly related to moose, but still... Does anybody know any article which does a survey of the questions that the users ask themselves when faced with the task of understanding a new software system? Thanks, Mircea.
