[Texo] ModelDataGenerator [message #1597433]

Hi Martin,

I just tried to write a test with a large amount of data. Therefore I tried to generate model data. I used your code in the Texo wiki:

final ModelDataGenerator modelDataGenerator = new ModelDataGenerator();
modelDataGenerator.setStartEClasses(eClasses);
modelDataGenerator.setMaxDepth(maxDepth);
modelDataGenerator.setCollectionSize(collectionSize);
modelDataGenerator.setDataSize(dataSize);
modelDataGenerator.setMaxObjects(maxObjects);
modelDataGenerator.setEPackages(ePackages);
modelDataGenerator.generateTestData();
System.err.println("Generated " + modelDataGenerator.getTotalObjectCount() + " objects ");
List<EObject> result = modelDataGenerator.getResult();

Then I wanted to save the data directly through an EntityManager. This won't work, since the all returned data are of type DynamicEObject. My assumption was the returned objects would be Texo model objects.
Converting those DynamicEObjects to the EMF model works. So persisting the EMF objects within a 2- or 3-Tier-Architecture would work. But in this test environment this would be a little detour.

Is the DynamicEObject usage mandatory or is just something configured incorrectly?

Best regards
Bastian

Hi Bastian,
There is a EMF --> Texo converter: EMFModelConverter, so you can call this after the data generation.

Hi Martin,

thanks, that was it. I just expected the getResult() method to return the Texo objects directly and not a DynamicEObject.

Best regards
Bastian
