Hi,

I am using IncQuery version 0.9.1 and creating patterns at run time. I have a few queries:

1. I am looking for a way to get transitive closure using IncQuery pattern creation at run time. I basically want to dynamically know what other EAttributes/EReference are being referenced by a given EObject in all the Ecore structures.

2. I also wanted to know if there is some way of getting a path in the EMF model from one EStructuralFeature to another dynamically using IncQuery. To be more specific, I am looking for some functionality which would fetch me a path from one EObject to another by just specifying the source and destination.
For instance, if my Ecore structure is named 'a' and I am looking for a EStructuralFeature 'd' which can be reached using the constraint a.b.c.d
However, there might be times when I don't know the exact path and would need some functionality like a*d which would fetch me 'd' without the full path either recursively or using transitive closure. Is there any way to achieve this using IncQuery?

Thanks
