Class	Description
AbstractStreamTaskNetworkInput<T,R extends RecordDeserializer<DeserializationDelegate<StreamElement>>>	Base class for network-based StreamTaskInput where each channel has a designated RecordDeserializer for spanning records.
BlockingQueueBroker	Broker for the BlockingQueue used in StreamIterationHead and StreamIterationTail for implementing feedback streams.
DataInputStatus	It is an internal equivalent of InputStatus that provides additional non public statuses.
FinishedDataOutput<IN>	An empty PushingAsyncDataInput.DataOutput which is used by StreamOneInputProcessor once an DataInputStatus.END_OF_DATA is received.
InputGateUtil	Utility for dealing with input gates.
MultipleFuturesAvailabilityHelper	This class is semi-thread safe.
MultipleInputSelectionHandler	This handler is mainly used for selecting the next available input index in StreamMultipleInputProcessor.
PushingAsyncDataInput<T>	The variant of PullingAsyncDataInput that is defined for handling both network input and source input in a unified way via PushingAsyncDataInput.emitNext(DataOutput) instead of returning Optional.empty() via PullingAsyncDataInput.pollNext().
PushingAsyncDataInput.DataOutput<T>	Basic data output interface used in emitting the next element from data input.
RecordAttributesCombiner	RecordAttributesValve combine RecordAttributes from different input channels.
RecordProcessorUtils	Utility class for creating record processor for Input StreamOperator.
RecordWriterOutput<OUT>	Implementation of Output that sends data using a RecordWriter.
RecoverableStreamTaskInput<T>	A StreamTaskInput used during recovery of in-flight data.
StreamInputProcessor	Interface for processing records by StreamTask.
StreamMultipleInputProcessor	Input processor for MultipleInputStreamOperator.
StreamMultipleInputProcessorFactory	A factory for StreamMultipleInputProcessor.
StreamOneInputProcessor<IN>	Input reader for OneInputStreamTask.
StreamTaskExternallyInducedSourceInput<T>	A subclass of StreamTaskSourceInput for ExternallyInducedSourceReader.
StreamTaskInput<T>	Basic interface for inputs of stream operators.
StreamTaskNetworkInput<T>	Implementation of StreamTaskInput that wraps an input from network taken from CheckpointedInputGate.
StreamTaskNetworkInputFactory	Factory for StreamTaskNetworkInput and RescalingStreamTaskNetworkInput.
StreamTaskSourceInput<T>	Implementation of StreamTaskInput that reads data from the SourceOperator and returns the DataInputStatus to indicate whether the source state is available, unavailable or finished.
StreamTwoInputProcessorFactory	A factory to create StreamMultipleInputProcessor for two input case.
