类和说明
AbstractTwoInputStreamTask Abstract class for executing a TwoInputStreamOperator.
AsyncExceptionHandler An interface marking a task as capable of handling exceptions thrown by different threads, other than the one executing the task itself.
AsynchronousException An exception for wrapping exceptions that are thrown by an operator in threads other than the main compute thread of that operator.
OneInputStreamTask A StreamTask for executing a OneInputStreamOperator.
OperatorChain The OperatorChain contains all operators that are executed as one chain within a single StreamTask.
OperatorChain.WatermarkGaugeExposingOutput An Output that measures the last emitted watermark with a WatermarkGauge.
ProcessingTimeCallback Interface for processing-time callbacks that can be registered at a ProcessingTimeService.
ProcessingTimeService Defines the current processing time and handles all related actions, such as register timers for tasks to be executed in the future.
StreamTask Base class for all streaming tasks.
StreamTaskActionExecutor Executes Runnable, ThrowingRunnable, or Callable.
StreamTaskActionExecutor.SynchronizedStreamTaskActionExecutor 已过时。 this class should only be used in SourceStreamTask which exposes the checkpoint lock as part of Public API. During transitional period it is used in StreamTask (until StreamTask.getCheckpointLock() is pushed down to SourceStreamTask).
TimerService A common timer service interface with life cycle methods.
