/**
 * Provides component specific methods to enable components to register their
 * Stats implementations for monitoring. Implementation of this interface enables
 * a JSR77 Managed Resource's monitoring statistics to be presented
 * through JMX's API through a DynamicMBean created on the fly
 * and registered with the MBeanServer. Each registration method also provides
 * the facility of passing in an implementation of MonitoringLevelListener interface.
 * The purpose of that interface is to enable components to be notified of a 
 * change in monitoring level from/to OFF, LOW or HIGH. A notification pursuant 
 * to a change in monitoring level should result in a call to unregister previously
 * registered Stats implementations. If the change is set at a level LOW or HIGH,
 * a call to register alternative Stats implementations that correspond to the 
 * new monitoring level is to be made by the component.  Consequently, a new MBean 
 * is registered with the MBeanServer so that clients may now request statistics 
 * corresponding to the monitoring level.<br>
 * Registered Stats implementations can be unregistered through the component 
 * specific unregister() methods.
