## Interface DynamicIntroductionAdvice

- All Superinterfaces:
    Advice
  All Known Subinterfaces:
    IntroductionInterceptor
  All Known Implementing Classes:
    DelegatePerTargetObjectIntroductionInterceptor, DelegatingIntroductionInterceptor

      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 {qlink 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.
