[henshin-dev] Interpreter Wizard

[Christian Krause <henshin.ck@xxxxxxxxx>]

Dear Gregor,
could you at some point revise the interpreter wizard? We currently have 
2 problems:

1) The Sierpinski example seems not to work in the wizard (but in the 
stand-alone Java app).

2) The wizard does not support models with multiple root objects. As an 
example you can take the Ecore2UML example. It should generate two UML 
packages ("ecore" and "flowchartdsl") which should be added as new root 
objects. Actually, all generated trace objects should also become root 
objects. If the model is too big, you can also try a smaller example.

In general, I recommend to construct an EGraph like this: new 
EGraphImpl(resource) or EGraph(eobject). Note that there are 2 new 
methods called addGraph(EObject) and removeGraph(EObject). In contrast 
to addTree(EObject), the new methods will add / remove all transitively 
reachable objects to the graph, and not just the children in the 
containment tree. When you transformed the graph, use getRoots() to 
obtain the root objects again.

Cheers,
Christian
