Direct Known Subclasses:
XMBean
public abstract class ModelMBeanInvoker
extends AbstractMBeanInvoker
implements ModelMBean, ModelMBeanConstants

After the interceptor configuration, this implementation invokes the load() method on this Model MBean instance. This will attempt to load a pre-existing management attribute state for this Model MBean instance. See the Javadoc for load() for more information.
