Interface Advisor
- All Known Subinterfaces:
- AfterReturningAdvisor, BeforeAdvisor, InterceptionAdvisor, InterceptionAroundAdvisor, InterceptionIntroductionAdvisor, IntroductionAdvisor, PointcutAdvisor, ThrowsAdvisor
- public interface Advisor
Base interface holding AOP advice (action to take at a joinpoint)
and a filter determining the applicability of the advice (such as
a pointcut). This interface is not for use by Spring users, but to
allow for commonality in support for different types of advice.
Spring currently supports around advice delivered via method
interception. However, this interface is intended to allow support for
different types of advice, such as before and after advice,
which need not be implemented using interception. Note that these advice
types can be implemented using around advice at present.
