类 MapBundleOperator<K,V,IN,OUT>

java.lang.Object

org.apache.flink.streaming.api.operators.AbstractStreamOperator<OUT>

org.apache.flink.table.runtime.operators.bundle.AbstractMapBundleOperator<K,V,IN,OUT>

org.apache.flink.table.runtime.operators.bundle.MapBundleOperator<K,V,IN,OUT>

所有已实现的接口:

Serializable, org.apache.flink.runtime.state.CheckpointListener, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.OneInputStreamOperator<IN,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, BundleTriggerCallback, org.apache.flink.util.Disposable

public class MapBundleOperator<K,V,IN,OUT>
extends AbstractMapBundleOperator<K,V,IN,OUT>

The MapBundleOperator uses a KeySelector to extract bundle key, thus can be used with non-keyed-stream.
