类 WindowOperatorBuilder

java.lang.Object

org.apache.flink.table.runtime.operators.window.WindowOperatorBuilder

public class WindowOperatorBuilder
extends Object

The WindowOperatorBuilder is used to build WindowOperator fluently.

Note: You have to call the aggregate method before the last build method.

 WindowOperatorBuilder
   .builder(KeyedStream)
   .tumble(Duration.ofMinutes(1))       // sliding(...), session(...)
   .withEventTime()     // withProcessingTime()
   .withAllowedLateness(Duration.ZERO)
   .produceUpdates()
   .aggregate(AggregationsFunction, accTypes, windowTypes)
   .build();
