021/**
022 * Subinterface of AOP Alliance MethodInterceptor that allows additional interfaces
023 * to be implemented by the interceptor, and available via a proxy using that
024 * interceptor. This is a fundamental AOP concept called <b>introduction</b>.
025 *
026 * <p>Introductions are often <b>mixins</b>, enabling the building of composite
027 * objects that can achieve many of the goals of multiple inheritance in Java.
