I have tried another way, it is not working as well:
def evaluationStream(
indicatorsStream: DataStream[Indicators],
scenarios: Set[Scenario]): DataStream[Evaluation] =
indicatorsStream.map(new IndicatorsToTxEval(scenarios))
class IndicatorsToTxEval(
scenarios: Set[Scenario])
extends MapFunction[Indicators, Evaluation] {
override def map(inds: Indicators): Evaluation =
Evaluation(indicators.id <http://indicator.id/>,
evaluateScenarios(indicators, scenarios))
}
Best regards/祝好,
