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

类和说明
DataInputStatus It is an internal equivalent of InputStatus that provides additional non public statuses.
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.
