Class Summary

Class	Description
AggregatorContainer	AccumT container for the current values associated with Aggregators.
AggregatorContainer.AggregatorKey	Aggregators are identified by a step name and an aggregator name.
AggregatorContainer.Mutator	AccumT class for mutations to the aggregator values.
CopyOnAccessInMemoryStateInternals<K>	StateInternals built on top of an underlying StateTable that contains instances of InMemoryStateInternals.InMemoryState.
DirectOptions.AvailableParallelismFactory	A DefaultValueFactory that returns the result of Runtime.availableProcessors() from the DirectOptions.AvailableParallelismFactory.create(PipelineOptions) method.
DirectRegistrar	Contains the PipelineRunnerRegistrar and PipelineOptionsRegistrar for the DirectRunner.
DirectRegistrar.Options	Registers the DirectOptions.
DirectRegistrar.Runner	Registers the DirectRunner.
DirectRunner	An In-Memory implementation of the Dataflow Programming Model.
DirectRunner.DirectPipelineResult	The result of running a Pipeline with the DirectRunner.
ForwardingPTransform<InputT extends PInput,OutputT extends POutput>	A base class for implementing PTransform overrides, which behave identically to the delegate transform but with overridden methods.
NanosOffsetClock	A Clock that uses System.nanoTime() to track the progress of time.
StepTransformResult<InputT>	An immutable TransformResult.
StepTransformResult.Builder<InputT>	A builder for creating instances of StepTransformResult.
WatermarkManager	Manages watermarks of PCollections and input and output watermarks of AppliedPTransforms to provide event-time and completion tracking for in-memory execution.
WatermarkManager.FiredTimers	A pair of TimerInternals.TimerData and key which can be delivered to the appropriate AppliedPTransform.
WatermarkManager.TimerUpdate	A collection of newly set, deleted, and completed timers.
WatermarkManager.TimerUpdate.TimerUpdateBuilder	A WatermarkManager.TimerUpdate builder that needs to be provided with set timers and deleted timers.
