org.apache.flink.streaming.api.functions.co.CoProcessFunction<I1,I2,O>

org.apache.flink.iteration.functions.EpochAwareCoProcessFunction<I1,I2,O>

所有已实现的接口:

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

@Internal
public abstract class EpochAwareCoProcessFunction<I1,I2,O>
extends org.apache.flink.streaming.api.functions.co.CoProcessFunction<I1,I2,O>
implements EpochAware

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