Hi Mariano,
For some reason your mail appeared as blocked for the mailing list. I
undid the setting now. Did you get the previous email of Simon?
Cheers,
Doru

Hi Moosers. I am doing little experiments to
export/serialize big
graph of objects using ImageSegment. I though that MooseModel was a
good candidate. And I even remember Simon's wishes for copying
them. But I have a couple of questions:
1) Which is the bigger autogenerated MooseModel I can get to test?
For the moment I am evaluating "MooseModel installDefaultModels".
and then I export "MooseModel root". Is there a bigger one I can
use? how ?
Take a look at the MooseScripts class, class-side. There are a
number of methods to create moose models from the image itself. In
order of importance: Network << Moose << Pharo
With network, you won't have any problem. With a model of Moose
itself, it's fast enough to do lots of test yet you can still
improve things. Then a Pharo model is certainly a good scalability
test.
2) How is the root or any other MooseModel normally exported?
Which methods? which technology ? Can you give me an example of the
standard way to export/serialize/copy a MooseModel ? The only
thing I saw is MooseModel class >> export: aModel to: aStream
I just open a file and send it as Stream?
Depends...
- File persistency is done in the MSE format and using Fame to
serialize entities in MSE.
Just take a look at MooseModel>>exportToMSEStream:
- To clone a model, just use MooseModelCopier>>copyModel: (this was
a simple experiment to make practical copies of large MooseModels.
Or rather to show that simple copy did not scale well on large
MooseModel right now).
3) Suppose that I copy/export somehow a MooseModel (suppose the
root) to a file. I take another Moose image, I load the file,
objects are alive again and I replace MooseModel rootModel with the
new object. How do I know if the copy/export worked correctly ?
If I do it in the same image, I can have both, but how can I
compare them to be sure everything was done ok ? method #= has no
sense as it will use Object with is #==. So...any idea to know if
the MooseModel I export and load again with ImageSegment is really
working or not?
I would change the tests setup to export/import the test model and
run tests on it (that's what I did to test the MooseModelCopier).
Only problem is that tests use some small models, so maybe some
things will be hidden. This is start though.
I want to test exporting and loading these MooseModel with
different technologies but I need a way to know if the resulted
object is correct or not.
Ahhh please, cc' me in the mail as I am not sure I receive emails
from this list.
Thanks for any hints.
Mariano
