org.apache.flink.streaming.api.operators使用的org.apache.flink.streaming.runtime.io中的类

类和说明
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.

类和说明
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.
