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 SunJmxMBeanServer.setMBeanServerInterceptor method.

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 ObjectName in the request.

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 virtual MBeans, 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.
