Examples of org.aopalliance.intercept.MethodInterceptor

org.aopalliance.intercept.MethodInterceptor
Intercepts calls on an interface on its way to the target. These are nested "on top" of the target.
The user should implement the {@link #invoke(MethodInvocation)}method to modify the original behavior. E.g. the following class implements a tracing interceptor (traces all the calls on the intercepted method(s)):
```
 class TracingInterceptor implements MethodInterceptor { Object invoke(MethodInvocation i) throws Throwable { System.out.println("method "+i.getMethod()+" is called on "+ i.getThis()+" with args "+i.getArguments()); Object ret=i.proceed(); System.out.println("method "+i.getMethod()+" returns "+ret); return ret; } } 
```
