IntroductionInterceptor
All Known Implementing Classes:

public interface DynamicIntroductionAdvice extends Advice
Subinterface of AOP Alliance Advice that allows additional interfaces to be implemented by an Advice, and available via a proxy using that interceptor. This is a fundamental AOP concept called introduction.

Introductions are often mixins, enabling the building of composite objects that can achieve many of the goals of multiple inheritance in Java.

Compared to IntroductionInfo, this interface allows an advice to implement a range of interfaces that is not necessarily known in advance. Thus an IntroductionAdvisor can be used to specify which interfaces will be exposed in an advised object.
