| [EWL/ETL] Model matching [message #557259] |

I'm trying to build a tool that looks for parts of a model that have a "specific form", and replaces them.
I specify this "specific form" using a model too, so what I need is to verify if any part of model match another model. We can see the models as graphs, so I want to check if a graph contains other graph.
Does EWL/ETL provide this kind of matching functionalities?
I think I should be able to implement this functions, but it will be a waste of time if Epsilon has this.
Thanks.

many model management tasks. If you decide to move forward with this,
it'd be great to keep in touch and explore the potentials for
collaboration and integration with Epsilon!

I have the match function almost implemented. However, my function only works with some models (in my case, each element can only have an input connection, so I was able to create a more efficient algorithm).
I could create a general algorithm, but, using EWL, the algorithm will depend on the meta-model. If you think there is some way to overcome this "problem" (maybe using Java?), let me know, and I try to implement this feature.

Yes. You'd probably need to use Java for a generic pattern matching
algorithm. You could even create a small task-specific language for this
using the infrastructure provided by Epsilon i.e.:
pattern Inheritance
find: c1:Class, c2:Class
where: c2.superTypes.includes(c1) and not c1.isAbstract
Does this sound sensible?
Cheers,
