Class	Description
AbstractTwoInputStreamTask<IN1,IN2,OUT>	Abstract class for executing a TwoInputStreamOperator.
ContainingTaskDetails	Details about the operator containing task (such as StreamTask).
ExceptionInChainedOperatorException	A special exception that signifies that the cause exception came from a chained operator.
FinishedOnRestoreInput<IN>	A fake Input for finished on restore tasks.
FinishedOnRestoreMainOperatorOutput<OUT>	A fake main operator output that skips all the following operators for finished on restored tasks.
FinishedOperatorChain<OUT,OP extends StreamOperator<OUT>>	The OperatorChain that is used for restoring tasks that are TaskStateManager.isTaskDeployedAsFinished().
MultipleInputStreamTask<OUT>	A StreamTask for executing a MultipleInputStreamOperator and supporting the MultipleInputStreamOperator to select input for reading.
OneInputStreamTask<IN,OUT>	A StreamTask for executing a OneInputStreamOperator.
OperatorChain<OUT,OP extends StreamOperator<OUT>>	The OperatorChain contains all operators that are executed as one chain within a single StreamTask.
OperatorChain.ChainedSource	Wrapper class to access the chained sources and their's outputs.
OperatorEventDispatcherImpl	An implementation of the OperatorEventDispatcher.
OutputWithChainingCheck<OUT>	This is a wrapper for outputs to check whether the collected record has been emitted to a downstream subtask or to a chained operator.
ProcessingTimeService	Defines the current processing time and handles all related actions, such as register timers for tasks to be executed in the future.
ProcessingTimeServiceAware	Interface for StreamOperatorFactory, which enables stream operators to access ProcessingTimeService.
ProcessingTimeServiceFactory	A factory for creating processing time services with a given MailboxExecutor.
ProcessingTimeServiceUtil	Utility for classes that implements the ProcessingTimeService interface.
RegularOperatorChain<OUT,OP extends StreamOperator<OUT>>	A regular non finished on restore OperatorChain.
SourceOperatorStreamTask<T>	A subclass of StreamTask for executing the SourceOperator.
SourceOperatorStreamTask.AsyncDataOutputToOutput<T>	Implementation of PushingAsyncDataInput.DataOutput that wraps a specific Output.
SourceStreamTask<OUT,SRC extends SourceFunction<OUT>,OP extends StreamSource<OUT,SRC>>	Deprecated. This class is based on the SourceFunction API, which is due to be removed.
StreamIterationHead<OUT>	A special StreamTask that is used for executing feedback edges.
StreamIterationTail<IN>	A special StreamTask that is used for executing feedback edges.
StreamOperatorWrapper<OUT,OP extends StreamOperator<OUT>>	This class handles the finish, endInput and other related logic of a StreamOperator.
StreamTask<OUT,OP extends StreamOperator<OUT>>	Base class for all streaming tasks.
StreamTask.CanEmitBatchOfRecordsChecker	Check whether records can be emitted in batch.
StreamTaskActionExecutor	Executes Runnable, ThrowingRunnable, or Callable.
StreamTaskActionExecutor.SynchronizedStreamTaskActionExecutor	Deprecated. this class should only be used in SourceStreamTask which exposes the checkpoint lock as part of Public API.
StreamTaskCancellationContext	Context on the StreamTask for figuring out whether it has been cancelled.
StreamTaskException	An exception that is thrown by the stream vertices when encountering an illegal condition.
StreamTaskFinishedOnRestoreSourceInput<T>	A special source input implementation that immediately emit END_OF_INPUT.
SubtaskCheckpointCoordinator	Coordinates checkpointing-related work for a subtask (i.e.
SystemProcessingTimeService	A TimerService which assigns as current processing time the result of calling System.currentTimeMillis() and registers timers using a ScheduledThreadPoolExecutor.
TimerException	RuntimeException for wrapping exceptions that are thrown in the timer callback of the timer service in StreamTask.
TimerService	A common timer service interface with life cycle methods.
TwoInputStreamTask<IN1,IN2,OUT>	A StreamTask for executing a TwoInputStreamOperator and supporting the TwoInputStreamOperator to select input for reading.
WatermarkGaugeExposingOutput<T>	An Output that measures the last emitted watermark with a WatermarkGauge.
