/**
|
|
* <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>
