Package net.sansa_stack.spark.rdd.function

Interface JavaPairRddFunction<KI,VI,KO,VO>

Type Parameters:

KI -

VI -

KO -

VO -

All Superinterfaces:

Function<org.apache.spark.api.java.JavaPairRDD<KI,VI>,org.apache.spark.api.java.JavaPairRDD<KO,VO>>, Serializable, org.aksw.commons.lambda.serializable.SerializableFunction<org.apache.spark.api.java.JavaPairRDD<KI,VI>,org.apache.spark.api.java.JavaPairRDD<KO,VO>>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface JavaPairRddFunction<KI,VI,KO,VO>
extends org.aksw.commons.lambda.serializable.SerializableFunction<org.apache.spark.api.java.JavaPairRDD<KI,VI>,org.apache.spark.api.java.JavaPairRDD<KO,VO>>

Interface for building chains of transformations over JavaRDDs and JavaPairRDDs. See JavaRddFunction for more information.
