public interface MethodInterceptor extends Interceptor
The user should implement the 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;
}
}
