Re: [henshin-dev] How to correctly build rules?

Hi Jens,

Henshin even seems to apply a transformation, but instead of adding
the desired stereotype, it (aims to) remove the two other stereotypes
(the one from aNode and the CommunicationPath) -- maybe I
misunderstood how transformation rules work here?
Could it be that the stereotypes are root nodes? If you execute your
transformation programmatically, try this: call graph.getRoots() to see
the root objects before and after the transformation. If they are in
fact roots, then you should see the added stereotype after the rule
application.
If that is as expected, all you need to do is to add the new root object
to the resource. A simple way of doing it would be:
resource.getContents().clear();
resource.getContents().addAll(graph.getRoots());
Then you can save the resource and everything should be as expected.
By the way: you should also make sure that the EGraph knows all the root
objects:
// Create and init the EGRaph:
EGraph graph = new EGraphImpl(resource);
...
This automatically adds all roots to the graph.
Hope it works. If you have questions, please ask..
Cheers,
Christian
