public class GraphMetrics
extends Object
implements org.apache.flink.api.common.ProgramDescription

This example illustrates how to use Gelly metrics methods and get simple statistics from the input graph. The program creates a random graph and computes and prints the following metrics: - number of vertices - number of edges - average node degree - the vertex ids with the max/min in- and out-degrees The input file is expected to contain one edge per line, with long IDs and no values, in the following format: "<sourceVertexID>\t<targetVertexID>". If no arguments are provided, the example runs with a random graph of 100 vertices.
