类 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.
