Class Edge<K,V>

java.lang.Object

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

org.apache.flink.api.java.tuple.Tuple3<K,K,V>

org.apache.flink.graph.Edge<K,V>

Type Parameters:

K - the key type for the sources and target vertices

V - the edge value type

All Implemented Interfaces:

Serializable

public class Edge<K,V>
extends Tuple3<K,K,V>

An Edge represents a link between two vertices, the source and the target and can carry an attached value. For edges with no value, use NullValue as the value type.
