Class Triplet<K,VV,EV>

java.lang.Object

org.apache.flink.api.java.tuple.Tuple

org.apache.flink.api.java.tuple.Tuple5<K,K,VV,VV,EV>

org.apache.flink.graph.Triplet<K,VV,EV>

Type Parameters:

K - the vertex key type

VV - the vertex value type

EV - the edge value type

All Implemented Interfaces:

Serializable

public class Triplet<K,VV,EV>
extends org.apache.flink.api.java.tuple.Tuple5<K,K,VV,VV,EV>

A Triplet stores and retrieves the edges along with their corresponding source and target vertices. Triplets can be obtained from the input graph via the Graph.getTriplets() method.
