I2 - type of values in the right set

OUT - type of resulting values

K - type of key

所有已实现的接口:

Serializable, org.apache.flink.api.common.functions.FlatJoinFunction<I1,org.apache.flink.api.java.tuple.Tuple2<K,I2>,OUT>, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.RichFunction

@Internal
public final class TupleRightUnwrappingJoiner<I1,I2,OUT,K>
extends WrappingFunction<org.apache.flink.api.common.functions.FlatJoinFunction<I1,I2,OUT>>
implements org.apache.flink.api.common.functions.FlatJoinFunction<I1,org.apache.flink.api.java.tuple.Tuple2<K,I2>,OUT>

Joiner that unwraps values from the right set before applying the join operation.
