public  void destroy()
This method is part of the interceptor lifecycle. It is called by the
invoker durin the interceptor removal.   


For shared interceptors the lifecycle is driven by the MBean
unregistration. This method is called after the MBean is registered to the
server as part of the 
javax.management.MBeanRegistration#postDeregister  execution.  


Concrete interceptor implementations can override this method to provide
cleanup code that should be executed once the interceptor is no longer
registered to the MBean server.

 public String getName()
Returns the name of this interceptor. Notice that for shared interceptors
this name must be unique among the shared interceptors in the MBean
server.

 public  void init() throws Exception
This method is part of the interceptor's lifecycle. It is
called by the invoker during the initialization of the interceptor
instance.        


For shared interceptors the lifecycle is driven by the MBean registration.
This method is called before the MBean is registered to the server.  


Concrete interceptor implementations can override this method to provide
initialization code that should be executed before the interceptor
is registered.   


Any exception that is propagated from this method to its caller will
cancel the interceptor registration.

 public Object invoke(Invocation invocation) throws Throwable
The invoke method is called when the invocation object passes
this interceptor.

 public boolean isShared()
Returns true if this interceptor is shared by multiple invokers;
false otherwise. Non-shared interceptors should always return false.
Shared interceptors return false if they have not been registered
to the MBean server yet. Shared interceptors must always return true
after they have been registered to the server.

 public  void setLogger(Logger log)
Called by the MBeanInvoker  on
a non-shared interceptors to set a logger reference for this interceptor.
The interceptor implementation may use the invoker's logger for recording
log information.   


Shared interceptors should set up their log facility through other means
as they are invoked by several different MBean invokers. To access the
log implementation of the originating invoker for a particular invocation,
an interceptor may query they invocation context for invoker reference.

 public  void start()
This method is part of the interceptor's lifecycle. It is
called by the invoker during the interceptor initialization process. 


For shared interceptors the lifecycle is driven by the MBean registration.
This method is called after the MBean is registered to the
server as part of the 
javax.management.MBeanRegistration#postRegister  execution.   


Concrete interceptor implementations can override this method to provide
initialization code that should be executed once the MBean server and
object name references for this interceptor have been resolved.

 public  void stop() throws Exception
This method is part of the interceptor lifecycle. It is 
called by the invoker during the interceptor removal.   


For shared interceptors the lifecycle is driven by the MBean
unregistration. This method is called after the MBean is registered to the
server as part of the 
javax.management.MBeanRegistration#preDeregister  execution.  


Concrete interceptor implementations can override this
method to provide cleanup code that should be executed before the
interceptor is unregistered.   


Any exception that is propagated from this method to its caller will
cancel the interceptor unregistration.
