public class ThreadManager

extends java.util.HashMap

implements ManagedThread

A class which starts off and manages a number of child threads. The child threads are located from class names in the "thread" properties file. The "threads" property in this properties file is a comma separated list of java class names. Each class must implement ManagedThread interface and have a constructor that takes ThreadManager as its first argument. This class will then have a new instance created. Once all these objects are created you will then be able to control them all together either by running each as a thread or shutting them all down together etc.
