[furcas-discussion] Reference Re-Evaluation Algorithm

[Uhl, Axel]

Hi Stephan,

good point. I planned to do that in getTokens(EObject) but then somehow forgot. Instead of simply fetching *all* tokens produced by the property from the mapping I of course need to filter for those tokens that contain the EObject sought in their referencedElements.

I'll change that accordingly.
