| 38 | /** | ||
| 39 | * <p>This interface specifies the behavior to be implemented by an | ||
| 40 | * MBean Server Interceptor. An MBean Server Interceptor has | ||
| 41 | * essentially the same interface as an MBean Server. An MBean Server | ||
| 42 | * forwards received requests to its default interceptor, which may | ||
| 43 | * handle them itself or forward them to other interceptors. The | ||
| 44 | * default interceptor may be changed via the {@link | ||
| 45 | * com.sun.jmx.mbeanserver.SunJmxMBeanServer#setMBeanServerInterceptor} | ||
| 46 | * method.</p> | ||
| 47 | * | ||
| 48 | * <p>The initial default interceptor provides the standard MBean | ||
| 49 | * Server behavior. It handles a collection of named MBeans, each | ||
| 50 | * represented by a Java object. A replacement default interceptor | ||
| 51 | * may build on this behavior, for instance by adding logging or | ||
| 52 | * security checks, before forwarding requests to the initial default | ||
| 53 | * interceptor. Or, it may route each request to one of a number of | ||
| 54 | * sub-interceptors, for instance based on the {@link ObjectName} in | ||
| 55 | * the request.</p> | ||
| 56 | * | ||
| 57 | * <p>An interceptor, default or not, need not implement MBeans as | ||
| 58 | * Java objects, in the way that the initial default interceptor does. | ||
| 59 | * It may instead implement <em>virtual MBeans</em>, which do not | ||
| 60 | * exist as Java objects when they are not in use. For example, these | ||
| 61 | * MBeans could be implemented by forwarding requests to a database, | ||
| 62 | * or to a remote MBean server, or by performing system calls to query | ||
| 63 | * or modify system resources.</p> | ||
