PushingAsyncDataInput
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
Basic data output interface used in emitting the next element from data input.

BlockingQueueBroker
Broker for the BlockingQueue used in StreamIterationHead and StreamIterationTail for implementing feedback streams. |
CheckpointBarrierHandler
The
CheckpointBarrierHandler reacts to checkpoint barrier arriving from the input
channels. |
CheckpointedInputGate
The
CheckpointedInputGate uses CheckpointBarrierHandler to handle incoming CheckpointBarrier from the InputGate . |
MultipleInputSelectionHandler
This handler is mainly used for selecting the next available input index in
StreamMultipleInputProcessor . |
PushingAsyncDataInput
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
Basic data output interface used in emitting the next element from data input.
|
StreamInputProcessor
Interface for processing records by
StreamTask . |
StreamTaskInput
Basic interface for inputs of stream operators.
|
StreamTaskSourceInput
Implementation of
StreamTaskInput that reads data from the SourceOperator and
returns the InputStatus to indicate whether the source state is available, unavailable or
finished. |
TwoInputSelectionHandler
This handler is mainly used for selecting the next available input index in
StreamTwoInputProcessor . |
Class and Description |
