Classes in org.apache.flink.api.java.operators used by org.apache.flink.api.java

Class and Description
AggregateOperator This operator represents the application of a "aggregate" operation on a data set, and the result data set produced by the function.
CoGroupOperator.CoGroupOperatorSets Intermediate step of a CoGroup transformation.
CrossOperator.DefaultCross A Cross transformation that wraps pairs of crossed elements into Tuple2.
CustomUnaryOperation
DataSink An operation that allows storing data results.
