public class AvailableTrackers
extends Object

Object Tracker Factory. This contains the tracker types available to the system, instantiates and dispenses Trackers to the system, and manages the instantiated Trackers. Trackers are made available to the system through a getInstance call, and all Tracker clients must notify the factory when a Tracker is no longer needed by calling release. Thread-safe!
