Remove object in place transformation [message #1861672]

Hi,

I have been trying to remove and object in an in place transformation in. QVTo but apparently there is not an expression that can directly do that. Any workarounds? thanks!

I addressed this be using the excluding() operation and returning the new set of elements excluding the one I wanted to remove. Not sure if it is the best way, but it seems to work :)

In truly declaration transformations there is no delete; just a deliberate failure to create/copy.

I tend to think of QVTo as semi-declarative. In this case the don't create/copy approach is applicable and so excluding from a copy is a sensible approach.

Hi

There is a removeElement(...) operation that you can invoke on the respective Model to remove a given Element from it. It should do what you want.

Kind regards
