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.
BroadcastConnectedStream<IN1,IN2>	A BroadcastConnectedStream represents the result of connecting a keyed or non-keyed stream, with a BroadcastStream with broadcast state(s).
BroadcastStream<T>	A BroadcastStream is a stream with broadcast state(s).
CachedDataStream<T>	CachedDataStream represents a DataStream whose intermediate result will be cached at the first time when it is computed.
CoGroupedStreams<T1,T2>	CoGroupedStreams represents two DataStreams that have been co-grouped.
CoGroupedStreams.UnionSerializer<T1,T2>	TypeSerializer for TaggedUnion.
CoGroupedStreams.UnionSerializerSnapshot<T1,T2>	The TypeSerializerSnapshot for the CoGroupedStreams.UnionSerializer.
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.
CustomSinkOperatorUidHashes	This class is responsible to hold operator Uid hashes from the common operators of the sink.
CustomSinkOperatorUidHashes.SinkOperatorUidHashesBuilder	Builder to construct CustomSinkOperatorUidHashes.
DataStream<T>	A DataStream represents a stream of elements of the same type.
DataStream.Collector<T>	This class acts as an accessor to elements collected via DataStream.collectAsync(Collector).
DataStreamSink<T>	A Stream Sink.
DataStreamSource<T>	The DataStreamSource represents the starting point of a DataStream.
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.
KeyedPartitionWindowedStream<T,KEY>	KeyedPartitionWindowedStream represents a data stream that collects all records with the same key separately into a full window.
KeyedStream<T,KEY>	A KeyedStream represents a DataStream on which operator state is partitioned by key using a provided KeySelector.
KeyedStream.IntervalJoin<T1,T2,KEY>	Perform a join over a time interval.
KeyedStream.IntervalJoined<IN1,IN2,KEY>	IntervalJoined is a container for two streams that have keys for both sides as well as the time boundaries over which elements should be joined.
NonKeyedPartitionWindowedStream<T>	NonKeyedPartitionWindowedStream represents a data stream that collects all records of each subtask separately into a full window.
PartitionWindowedStream<T>	PartitionWindowedStream represents a data stream that collects all records of each partition separately into a full window.
QueryableStateStream<K,V>	Deprecated. The Queryable State feature is deprecated since Flink 1.18, and will be removed in a future Flink major version.
SideOutputDataStream<T>	A SideOutputDataStream represents a DataStream that contains elements that are emitted from upstream into a side output with some tag.
SingleOutputStreamOperator<T>	SingleOutputStreamOperator represents a user defined transformation applied on a DataStream with one predefined output type.
StreamProjection<IN>	The result of DataStream.project(int...).
UnsupportedTimeCharacteristicException	An exception that indicates that a time characteristic was used that is not supported in the current operation.
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.
