Method Detail

clearback to summary
pack-priv void clear()
registerback to summary
public void register(MBeanImpl mb) throws InstanceAlreadyExistsException, MBeanRegistrationException, NotCompliantMBeanException

Handle registration of this MBean. If we are suspended, simply add to the deferredRegistrationList and mark the MBean as suspended. If we are not suspended, then register if JMX registration is enabled.

Parameters
mb:MBeanImpl

The MBeanImpl to register

resumeRegistrationback to summary
public void resumeRegistration()

Decrement the suspended registration count. If the count goes to zero. all registrations that occurred while suspendCount > 0 are registered with the JMX server, UNLESS isJMXRegistrationEnabled is false, in which case we simply clear the deferredRegistrations list, because all MBean will be registered once the root is available.

setRootback to summary
public void setRoot(MBeanImpl root) throws InstanceAlreadyExistsException, MBeanRegistrationException, NotCompliantMBeanException

Set the MBeanImpl that is the root of this MBean tree. Must be set before other methods are called (but this is not enforced).

Parameters
root:MBeanImpl

The root of the tree.

suspendRegistrationback to summary
public void suspendRegistration()

Increment the suspended registration count. All registrations with JMX are suspended while suspendCount > 0.

unregisterback to summary
public void unregister(MBeanImpl mb) throws InstanceNotFoundException, MBeanRegistrationException

Unregister the MBean. If we are suspended, remove from the deferredRegistrations list and mark suspended false. In any case, we unregister from JMX if JMX registration is enabled. Note that we may call unregister on an unregistered object if suspendCount > 0, but that's OK, because MBean.unregister does nothing if mb is not registered.

Parameters
mb:MBeanImpl

The MBean to unregister.
