Class Summary

Class	Description
AllWindowedStream<T,W extends Window>	A AllWindowedStream represents a data stream where the stream of elements is split into windows based on a WindowAssigner.
CoGroupedStreams<T1,T2>	CoGroupedStreams represents two DataStreams that have been co-grouped.
CoGroupedStreams.TaggedUnion<T1,T2>	Internal class for implementing tagged union co-group.
CoGroupedStreams.WithWindow<T1,T2,KEY,W extends Window>	A co-group operation that has KeySelectors defined for both inputs as well as a WindowAssigner.
ConnectedStreams<IN1,IN2>	ConnectedStreams represent two connected streams of (possibly) different data types.
DataStream<T>	A DataStream represents a stream of elements of the same type.
DataStreamSink<T>	A Stream Sink.
DataStreamSource<T>	The DataStreamSource represents the starting point of a DataStream.
IterativeStream<T>	The iterative data stream represents the start of an iteration in a DataStream.
IterativeStream.ConnectedIterativeStreams<I,F>	The IterativeStream.ConnectedIterativeStreams represent a start of an iterative part of a streaming program, where the original input of the iteration and the feedback of the iteration are connected as in a ConnectedStreams.
JoinedStreams<T1,T2>	JoinedStreams represents two DataStreams that have been joined.
JoinedStreams.WithWindow<T1,T2,KEY,W extends Window>	A join operation that has KeySelectors defined for both inputs as well as a WindowAssigner.
KeyedStream<T,KEY>	A KeyedStream represents a DataStream on which operator state is partitioned by key using a provided KeySelector.
SingleOutputStreamOperator<T>	SingleOutputStreamOperator represents a user defined transformation applied on a DataStream with one predefined output type.
SplitStream<OUT>	The SplitStream represents an operator that has been split using an OutputSelector.
StreamProjection<IN>
WindowedStream<T,K,W extends Window>	A WindowedStream represents a data stream where elements are grouped by key, and for each key, the stream of elements is split into windows based on a WindowAssigner.
