Class and Description |
---|
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() . |
Class and Description |
---|
BlockingQueueBroker
Broker for the BlockingQueue used in
StreamIterationHead and
StreamIterationTail for implementing feedback
streams. |
BufferStorage
The
BufferStorage takes the buffers and events from a data stream and adds them in a sequence. |
CheckpointBarrierHandler
The
CheckpointBarrierHandler reacts to checkpoint barrier arriving from the input channels. |
CheckpointedInputGate
The
CheckpointedInputGate uses CheckpointBarrierHandler to handle incoming
CheckpointBarrier from the InputGate . |
InputStatus
An
InputStatus indicates one input state which might be currently
available, not available or already finished. |
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.
|
TwoInputSelectionHandler
This handler is mainly used for selecting the next available input index
in
StreamTwoInputProcessor . |
Class and Description |
---|
PushingAsyncDataInput.DataOutput
