Load model from resource [message #81650] Mon, 19 May 2008 15:05 Go to next message

Hi there,

I am currently working on a chain of transformation from java to kdm and I
have
a little problem with model loading.

Until now what I do is
-Create a java model and put it in a Resource
-Save the resource as xmi file
-Load the file as an ASMModel with
ASMModel org.eclipse.m2m.atl.engine.AtlEMFModelHandler.loadModel(Stri ng
name, ASMModel metamodel, URI uri)

and use it as input for my ATL transformation javaModelToKdmModel

It works fine but I would like to skip the save step so I now use the
method

org.eclipse.m2m.atl.drivers.emf4atl.ASMEMFModel.loadASMEMFMo del(String
name, ASMEMFModel metamodel, Resource extent, ModelLoader ml) which takes
a Resource as parameter

It doesn't work. I suspect it is because the java Model contained in my
Resource is not an ASMModel. It is a model I create using classes
generated by the EMF wizard and my .ecore metamodel.

If I'm right, is it possible to load my model anyway? Otherwise what am I
missing?

Thanks in advance for your help

If you already have your Java model stored as an EMF resource, you can
normally use the resource URI in order to directly load the model
(within the ATL model handler) without serializing it.

Resource javaModel = ...
AtlEMFModelHandler atlEMFmh = ...
...
ASMModel javaMetamodel = ...
...
atlEMFmh.loadModel("javaModelName", javaMetamodel, javaModel.getURI());


Do you have already tested this?

Yes I already tried this. The problem is that I am not sure what URI I
should use to set the Resource URI. Since there is no file associated to
the Resource, I get a File not found exception when loadModel method
internally calls getResource
