Class Graph

java.lang.Object
  gps.network.graph.Graph

public class Graph
extends java.lang.Object

graph is an object representing network topology. this file is based on KOM / LetsQoS Topology Conversion Tools. Two ways to add a node: Instanciate a Node object and call graph.addNode() to get back the key of the node. Or call graph.newNode() to get back a new node that is already added to the graph. Same for adding new links.
