Constructor Detail

SingletonEdgeGraph

public SingletonEdgeGraph(ExecutionEnvironment env,
                          long vertexPairCount)

An undirected Graph containing one or more isolated two-paths. The in- and out-degree of every vertex is 1. For n vertices there are n/2 components.

Parameters:

env - the Flink execution environment

vertexPairCount - number of pairs of vertices
