所有已实现的接口:

Serializable, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.api.java.typeutils.ResultTypeQueryable<OUT>, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.KeyContextHandler, DataStreamPythonFunctionOperator<OUT>, org.apache.flink.streaming.api.operators.SetupableStreamOperator<OUT>, org.apache.flink.streaming.api.operators.StreamOperator<OUT>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator, org.apache.flink.streaming.api.operators.YieldingOperator<OUT>

封闭接口:

DelegateOperatorTransformation<OUT>

public static class DelegateOperatorTransformation.DelegateOperator<OUT>
extends AbstractPythonFunctionOperator<OUT>
implements DataStreamPythonFunctionOperator<OUT>

DelegateOperatorTransformation.DelegateOperator holds configurations, e.g. OutputTags, which will be applied to the actual python operator at translation stage.
