org.apache.flink.iteration.operator.TailOperator

所有已实现的接口:

Serializable, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.streaming.api.operators.Input<IterationRecord<?>>, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.OneInputStreamOperator<IterationRecord<?>,Void>, org.apache.flink.streaming.api.operators.SetupableStreamOperator<Void>, org.apache.flink.streaming.api.operators.StreamOperator<Void>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator

public class TailOperator
extends org.apache.flink.streaming.api.operators.AbstractStreamOperator<Void>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<IterationRecord<?>,Void>

The tail operators is attached after each feedback operator to increment the round of each record.
