Examples of org.springframework.aop.Advisor

org.springframework.aop.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 AOP is based around around advice delivered via method interception, compliant with the AOP Alliance interception API. The Advisor interface allows support for different types of advice, such as before and after advice, which need not be implemented using interception. @author Rod Johnson
