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().

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

类和说明
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.
