    • PhysicalTopology

      public PhysicalTopology​(org.w3c.dom.Element xml)
      Creates a new PhysicalTopology object. Takes the XML file containing all the information about the simulation environment and uses it to populate the PhysicalTopology object. The physical topology is basically composed of nodes connected by links, each supporting different wavelengths.
      Parameters:
      xml - file that contains the simulation environment information
