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
