Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.RichFunction, EpochAware

@Internal
public abstract class EpochAwareAllRoundProcessFunction<I,O>
extends org.apache.flink.streaming.api.functions.ProcessFunction<I,O>
implements EpochAware

A specialized ProcessFunction that also provide the attach epoch with each record. It is executed as all-round inside the iteration.
