org.apache.flink.api.java.operators.Operator<OUT,O>

org.apache.flink.api.java.operators.SingleInputOperator<IN,IN,ScalaAggregateOperator<IN>>

org.apache.flink.api.scala.operators.ScalaAggregateOperator<IN>

Type Parameters:

IN - The type of the data set aggregated by the operator.

Deprecated.

All Flink Scala APIs are deprecated and will be removed in a future Flink major version. You can still build your application in Scala, but you should move to the Java version of either the DataStream and/or Table API.

@Deprecated
 @Public
public class ScalaAggregateOperator<IN>
extends org.apache.flink.api.java.operators.SingleInputOperator<IN,IN,ScalaAggregateOperator<IN>>

This operator represents the application of a "aggregate" operation on a data set, and the result data set produced by the function.
