comparison flys-artifacts/src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java @ 687:06689035024c facets-slt
Added a compute() method to WINFOArtifact which acts as a dispatcher for different computations. It triggers a calculation based on ComputeCallbacks that are generated by the current states.
