- All Superinterfaces:
- PlatformManagedObject
The management interface for the logging facility.
 
There is a single global instance of the PlatformLoggingMXBean.
 The ManagementFactory.getPlatformMXBean method can be used to obtain
 the PlatformLoggingMXBean object as follows:
 
     PlatformLoggingMXBean logging = ManagementFactory.getPlatformMXBean(PlatformLoggingMXBean.class);
 
 The PlatformLoggingMXBean object is also registered with the
 platform MBeanServer.
 The ObjectName for uniquely
 identifying the PlatformLoggingMXBean within an MBeanServer is:
 
      java.util.logging:type=Logging
