| /** |
| * <p>This interface specifies the behavior to be implemented by an |
| * MBean Server Interceptor. An MBean Server Interceptor has |
| * essentially the same interface as an MBean Server. An MBean Server |
| * forwards received requests to its default interceptor, which may |
| * handle them itself or forward them to other interceptors. The |
| * default interceptor may be changed via the {@link |
| * com.sun.jmx.mbeanserver.SunJmxMBeanServer#setMBeanServerInterceptor} |
| * method.</p> |
| * |
| * <p>The initial default interceptor provides the standard MBean |
| * Server behavior. It handles a collection of named MBeans, each |
| * represented by a Java object. A replacement default interceptor |
| * may build on this behavior, for instance by adding logging or |
| * security checks, before forwarding requests to the initial default |
| * interceptor. Or, it may route each request to one of a number of |
| * sub-interceptors, for instance based on the {@link ObjectName} in |
| * the request.</p> |
| * |
| * <p>An interceptor, default or not, need not implement MBeans as |
| * Java objects, in the way that the initial default interceptor does. |
| * It may instead implement <em>virtual MBeans</em>, which do not |
| * exist as Java objects when they are not in use. For example, these |
| * MBeans could be implemented by forwarding requests to a database, |
| * or to a remote MBean server, or by performing system calls to query |
| * or modify system resources.</p> |
