com.sun.enterprise.admin.monitor.registry.StatsHolder
Provides the ability to associate various j2ee components and sub components in a hierarchical tree. Holds references to underlying Stats objects. On instantiation, the Stats object is converted to a DynamicMBean instance. When monitoring level is changed from OFF to LOW or HIGH, the MBean is registered with an MBeanServer. Calls made to the MBean are delegated to this object which in turn delegates it to underlying Stats object. @author Shreedhar Ganapathy
