Can a mapping call itself? [message #1061769]

Hi!

Is there a simple keyword to call a mapping again from its inside? So the mapping should recall itself based on a condition.

Thanks and regards.

Hi

Have you tried to just call as with any other mapping?

I would expect it to be like a recursive call in many languages. It
works fine until you run out of stack so you must have some guard that
limits infinite recursion.

Calling a mapping recursively is usually of little avail, unless you change the input to the mapping on every recursive call. For one and the same input, QVTo does not support recursion since it obtains the previously mapped target element from the trace.
