Class TopologyManager

java.lang.Object
  net.clackrouter.topology.core.TopologyManager

public class TopologyManager
extends java.lang.Object

Controls loading routers from different topology files and cleaning up on close.

Owns a hashtable of different TopologyModel objects, associated with their respective topology number. Can parse a topology node, adds each router specified by the file.
