## Package org.springframework.aop

Core Spring AOP interfaces, built on AOP Alliance AOP interoperability interfaces.

Description

Interface Summary
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).
AfterAdvice: Common marker interface for after advice, such as `AfterReturningAdvice` and `ThrowsAdvice`.
AfterReturningAdvice: After returning advice is invoked only on normal method return, not if an exception is thrown.
BeforeAdvice: Common marker interface for before advice, such as `MethodBeforeAdvice`.
ClassFilter: Filter that restricts matching of a pointcut or introduction to a given set of target classes.
DynamicIntroductionAdvice: Subinterface of AOP Alliance Advice that allows additional interfaces to be implemented by an Advice, and available via a proxy using that interceptor.
IntroductionAdvisor: Superinterface for advisors that perform one or more AOP introductions.
IntroductionAwareMethodMatcher: A specialized type of MethodMatcher that takes into account introductions when matching methods.
IntroductionInfo: Interface supplying the information necessary to describe an introduction.
IntroductionInterceptor: Subinterface of AOP Alliance MethodInterceptor that allows additional interfaces to be implemented by the interceptor, and available via a proxy using that interceptor.
MethodBeforeAdvice: Advice invoked before a method is invoked.
MethodMatcher: Part of a `Pointcut`: Checks whether the target method is eligible for advice.
Pointcut: Core Spring pointcut abstraction.
PointcutAdvisor: Superinterface for all Advisors that are driven by a pointcut.
ProxyMethodInvocation: Extension of the AOP Alliance `MethodInvocation` interface, allowing access to the proxy that the method invocation was made through.
RawTargetAccess: Marker for AOP proxy interfaces (in particular: introduction interfaces) that explicitly intend to return the raw target object (which would normally get replaced with the proxy object when returned from a method invocation).
SpringProxy: Marker interface implemented by all AOP proxies.
TargetClassAware: Minimal interface for exposing the target class behind a proxy.
TargetSource: A `TargetSource` is used to obtain the current "target" of an AOP invocation, which will be invoked via reflection if no around advice chooses to end the interceptor chain itself.
ThrowsAdvice: Tag interface for throws advice.

Exception Summary
AopInvocationException: Exception that gets thrown when an AOP invocation failed because of misconfiguration or unexpected runtime issues.

## Package org.springframework.aop Description

Core Spring AOP interfaces, built on AOP Alliance AOP interoperability interfaces.
Any AOP Alliance MethodInterceptor is usable in Spring.
Spring AOP also offers:

- Introduction support
- A Pointcut abstraction, supporting "static" pointcuts (class and method-based) and "dynamic" pointcuts (also considering method arguments). There are currently no AOP Alliance interfaces for pointcuts.
- A full range of advice types, including around, before, after returning and throws advice.
- Extensibility allowing arbitrary custom advice types to be plugged in without modifying the core framework.

Spring AOP can be used programmatically or (preferably) integrated with the Spring IoC container.
