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
