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?

Example of error range in senders:
FAMIX does not model shared variables and their initializers, thus
any sender in an initializer is lost. 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 :)

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?
Cheers,
Alexandre

Hi,
is there a good web site about oo metrics ? I need to get an overview
over different metrics (independent if moose implement them or not)

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
