Method Detail

preRegister

public ObjectName preRegister(MBeanServer server,
                              ObjectName name)
                       throws Exception

Description copied from class: javax.management.StandardMBean

Allows the MBean to perform any operations it needs before being registered in the MBean server. If the name of the MBean is not specified, the MBean can provide a name for its registration. If any exception is raised, the MBean will not be registered in the MBean server.

The default implementation of this method returns the name parameter. It does nothing else for Standard MBeans. For MXBeans, it records the MBeanServer and ObjectName parameters so they can be used to translate inter-MXBean references.

It is good practice for a subclass that overrides this method to call the overridden method via super.preRegister(...). This is necessary if this object is an MXBean that is referenced by attributes or operations in other MXBeans.

Specified by:

preRegister in interface MBeanRegistration

Overrides:

preRegister in class StandardMBean

Parameters:

server - The MBean server in which the MBean will be registered.

name - The object name of the MBean. This name is null if the name parameter to one of the createMBean or registerMBean methods in the MBeanServer interface is null. In that case, this method must return a non-null ObjectName for the new MBean.

Returns:

The name under which the MBean is to be registered. This value must not be null. If the name parameter is not null, it will usually but not necessarily be the returned value.

Throws:

IllegalArgumentException - if this is an MXBean and name is null.

InstanceAlreadyExistsException - if this is an MXBean and it has already been registered under another name (in this MBean Server or another).

Exception - no other checked exceptions are thrown by this method but Exception is declared so that subclasses can override the method and throw their own exceptions.

unregisterMBeans

public void unregisterMBeans()

Description copied from interface: MissionControlMXBean

Unregister all Mission Control related MBeans/MXBeans from the MBean server.

Specified by:

unregisterMBeans in interface MissionControlMXBean

registerMBeans

public void registerMBeans()

Description copied from interface: MissionControlMXBean

Register all Mission Control related MBeans/MXBeans with the MBean server. If one or more MBeans can't be registered, for whatever reason, the method will do a best effort and register as many MBeans as possible.

Specified by:

registerMBeans in interface MissionControlMXBean
