java.lang.Object

org.apache.hivemind.management.impl.MBeanRegistryImpl

All Implemented Interfaces:

java.util.EventListener, org.apache.hivemind.events.RegistryShutdownListener, MBeanRegistry

public class MBeanRegistryImpl
extends java.lang.Object
implements MBeanRegistry, org.apache.hivemind.events.RegistryShutdownListener

Implementation of MBeanRegistry. Registers MBeans in an standard JMX MBeanServer Supports calling start methods, after the registration. MBeans can be provided as service references in a configuration. Standard MBeans must use the primitive service model. Any interceptor destroys JMX compliance due to naming conventions. Implements shutdown listener to unregisters all MBeans when the registry is shutdown
