* Interceptor to wrap a MethodBeforeAdvice. In future we may also offer a more
* efficient alternative solution in cases where there is no interception advice
* and therefore no need to create a MethodInvocation object.
*
* Used internally by the AOP framework: application developers should not need
* to use this class directly.
*
*
You can use this class to wrap Spring MethodBeforeAdvice implementations
* for use in other AOP frameworks supporting the AOP Alliance
* interfaces.
