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