public class EvalWrapper extends AbstractNodeDecoratorRemove
Wraps an evaluator for the editor. Any editor component that has content that depends on evaluation, may listen to this object via the editor and be notified of any change. In particular, changes involve changes in the input parameters. This wrapper makes sure that it returns an evaluator based on the current input parameters and selected scenario in the editor.
