Class ThreadRegistry

java.lang.Object
  java.util.AbstractMap
      verinec.netsim.util.tables.ThreadRegistry

All Implemented Interfaces:

Map

public class ThreadRegistry
extends AbstractMap

The ThreadRegistry saves the assocation between thread and node. In other words it saves on which node the thread is running. Since only instance of the registry is wanted it has no public constructor. Use instead getInstance()to get an instance of the registry.
