comparison flys-artifacts/src/main/java/de/intevation/flys/artifacts/model/fixings/FixDerivateFacet.java @ 4442:26774405c884
Introduce a new FixingsFacet to add save access to the current Km
Values which are accessed by a String like a map must be checked for null. The
new FixingsFacet adds a getCurrentKm method that abstracts the direct access to
the CallContext and always returns a valid double value.
