* Implementation of {@link org.apache.hivemind.management.ObjectNameBuilder}A configurable domain

|

30 |
* key properties. Example for a service:
|

31 |
* HiveMind:module=hivemind,type=servicePoint,id=hivemind.Startup When using this naming Jconsole
|
|
32 |
* interprets the module key as package name and id as a class name.
