When an advice is applied to a Target, it becomes a Proxy. To the clients of the Target, the Target (Pre-AOP) and the Proxy (Post-AOP) are the same. There are no differences in the public APIs exposed by both of the objects. The Delta between the proxy and the target is the implementation to address cross-cutting concerns that are hosted in the Advice.
