java.lang.Objectit.unimi.dsi.webgraph.Stats
public class Stats
Computes basic statistical data about a given graph.
This class loads a graph of given basename, and computes the following data:
StronglyConnectedComponents
are present
(in particular, buckets and component sizes).
The graph is loaded offline: the only memory allocated is for indegree count (one integer per node) and for storing the actual counts (one integer per indegree/outdegree value).
