Method Detail

invoke

public Object invoke(Invocation invocation)
              throws InvocationException

Description copied from class: AbstractInterceptor

The default invoke implementation queries the invocation object for the next interceptor in the chain. If one exists, it is invoked. Otherwise the invocation is dispatched to the target object.

Concrete implementations should override this method to implement their specific application logic.

Specified by:: invoke in interface Interceptor
Overrides:: invoke in class AbstractInterceptor

Parameters:: invocation - the invocation object send towards the target resource by the invoker
Returns:: return value from the target resource
Throws:: InvocationException - This exception wraps any exceptions thrown by either the target method of the resource object, or invocation interceptors in this interceptor chain. The target exception is unwrapped at the MBeanInvoker instance.
