DefaultMBeanServerInterceptor

public class DefaultMBeanServerInterceptor extends Object implements MBeanServerInterceptor
This is the default class for MBean manipulation on the agent side. It contains the methods necessary for the creation, registration, and deletion of MBeans as well as the access methods for registered MBeans. This is the core component of the JMX infrastructure.

Every MBean which is added to the MBean server becomes manageable: its attributes and operations become remotely accessible through the connectors/adaptors connected to that MBean server. A Java object cannot be registered in the MBean server unless it is a JMX compliant MBean.

When an MBean is registered or unregistered in the MBean server an {@link javax.management.MBeanServerNotification MBeanServerNotification} Notification is emitted. To register an object as listener to MBeanServerNotifications you should call the MBean server method {@link #addNotificationListener addNotificationListener} with ObjectName the ObjectName of the {@link javax.management.MBeanServerDelegate MBeanServerDelegate}. This ObjectName is:
JMImplementation:type=MBeanServerDelegate.

Constructors Summary
public DefaultMBeanServerInterceptor(String domain, MBeanServer outer, MBeanServerDelegate delegate, MBeanInstantiator instantiator)
Creates a DefaultMBeanServerInterceptor with the specified default domain name. The default domain name is used as the domain part in the ObjectName of MBeans if no domain is specified by the user.

Do not forget to call initialize(outer,delegate) before using this object.

param
domain The default domain name used by this MBeanServer.
param
outer A pointer to the MBeanServer object that must be passed to the MBeans when invoking their {@link javax.management.MBeanRegistration} interface.
param
delegate A pointer to the MBeanServerDelegate associated with the new MBeanServer. The new MBeanServer must register this MBean in its MBean repository.
param
instantiator The MBeanInstantiator that will be used to instantiate MBeans and take care of class loading issues.
