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. It also represents the DataSet that is the result of a Cross transformation.
CustomUnaryOperation
DataSink
DataSource An operation that creates a new data set (data source).
DeltaIteration The DeltaIteration represents the start of a delta iteration.
DistinctOperator This operator represents the application of a "distinct" function on a data set, and the result data set produced by the function.
