Hi
I wanted to import a model from a stream
I did the following:
m := SCG.Moose.MooseModel new.
loader SCG.Moose.MooseImporter withActiveMetamodel.
loader importSTream: NameMatchingTest lanModel readStream.
Now I do not know how I can specify in which model the resulting
entities should be added.
When I use an SmalltalkImporter I usually do it that way:
m := SCG.Moose.MooseModel new.
PundleImporter new
model: m ;
addPundleNamed: 'xxx' ;
run
and m is populated.
So Importer is not following the same pattern or I'm stupid and in
both cases this is annoying.

Hi Stef,
In its current form, the MooseImporter just returns the top level
entity from MSE, and the convention is that an MSE file is enclosed
with (Moose.Model (entity ...) ). This means that the top level entity
is Moose.Model and everything inside is put in the entities.
To add this model to the root model you should do:
loader := SCG.Moose.MooseImporter withActiveMetamodel.
m := loader importSTream: NameMatchingTest lanModel readStream.
MooseModel root add: m.
This will probably change slightly in FAMIX 3.0 and in the Fame based
descriptions and format.

My main concern is that we have two design for importing things in
moose.
One is functional and you have to know that you get a model back
and the other is by side effect.
Too bad that we are not consistent.

You are right, and that should change once we move to the new
infrastructure.

Hi Doru,
You are right, and that should change once we move to the new
infrastructure.
What is the new infrastructure? Are you thinking in changing some core
classes in FAMIX?
We should know in advance, because I am programming with the actual
FAMIX and I would like to minimize the impact of changes in my application.
Cheers,
Gabi

The new infrastructure refers to:
- Fame is a simpler engine to replace Meta. This should have almost no
impact on a client code.
- FAMIX 3.0 is an improvement over the current FAMIX (a bit cleaner
names and some refactoring of the class hierarchy). The changes are
not that large and if you do not depend on some implementation issues,
the impact should again be small. However, the new FAMIX resides in a
namespace of its own, which means that the old FAMIX will be able to
coexist with the new FAMIX and the transition can be made smooth.
Cheers,
Doru
