[great-users] RTTGenerator

[Kevin Smyth]

Hi Valentin,

The idea is that the transformation can note what FCO in the input model
corresponds to which FCO in the output model. You can do this in your
transformation's Rule by creating a TracesTo connection between
PatternClasses.

If you have no TracesTo connections in your transform, I wouldn't think the
performance impact is noticeable. Have you measured the performance?
