Package org.apache.flink.table.runtime.operators.bundle

Class 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>

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.streaming.api.operators.Input<IN>, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.KeyContextHandler, org.apache.flink.streaming.api.operators.OneInputStreamOperator<IN,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>, BundleTriggerCallback

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.
