AopUtils

abstract class AopUtils

Utility methods for AOP support code.

Mainly for internal use within Spring's AOP support.

See org.springframework.aop.framework.AopProxyUtils for a collection of framework-specific AOP utility methods which depend on internals of Spring's AOP framework implementation.

Functions

canApply	`open static fun canApply(pc: Pointcut, targetClass: Class<>): Boolean` `open static fun canApply(pc: Pointcut, targetClass: Class<>, hasIntroductions: Boolean): Boolean` Can the given pointcut apply at all on the given class? This is an important test as it can be used to optimize out a pointcut for a class. `open static fun canApply(advisor: Advisor, targetClass: Class<>): Boolean` Can the given advisor apply at all on the given class? This is an important test as it can be used to optimize out a advisor for a class. `open static fun canApply(advisor: Advisor, targetClass: Class<>, hasIntroductions: Boolean): Boolean` Can the given advisor apply at all on the given class? This is an important test as it can be used to optimize out a advisor for a class. This version also takes into account introductions (for IntroductionAwareMethodMatchers).
findAdvisorsThatCanApply	`open static fun findAdvisorsThatCanApply(candidateAdvisors: MutableList<Advisor>, clazz: Class<*>): MutableList<Advisor>` Determine the sublist of the `candidateAdvisors` list that is applicable to the given class.
getMostSpecificMethod	`open static fun getMostSpecificMethod(method: Method, targetClass: Class<>): Method` Given a method, which may come from an interface, and a target class used in the current AOP invocation, find the corresponding target method if there is one. E.g. the method may be `IFoo.bar()` and the target class may be `DefaultFoo`. In this case, the method may be `DefaultFoo.bar()`. This enables attributes on that method to be found. NOTE:* In contrast to `org.springframework.util.ClassUtils#getMostSpecificMethod`, this method resolves Java 5 bridge methods in order to retrieve attributes from the original method definition.
getTargetClass	`open static fun getTargetClass(candidate: Any): Class<*>` Determine the target class of the given bean instance which might be an AOP proxy. Returns the target class for an AOP proxy or the plain class otherwise.
invokeJoinpointUsingReflection	`open static fun invokeJoinpointUsingReflection(target: Any, method: Method, args: Array<Any>): Any` Invoke the given target via reflection, as part of an AOP method invocation.
isAopProxy	`open static fun isAopProxy(object: Any): Boolean` Check whether the given object is a JDK dynamic proxy or a CGLIB proxy. This method additionally checks if the given object is an instance of SpringProxy.
isCglibProxy	`open static fun isCglibProxy(object: Any): Boolean` Check whether the given object is a CGLIB proxy. This method goes beyond the implementation of `ClassUtils#isCglibProxy(Object)` by additionally checking if the given object is an instance of SpringProxy.
isEqualsMethod	`open static fun isEqualsMethod(method: Method): Boolean` Determine whether the given method is an "equals" method.
isFinalizeMethod	`open static fun isFinalizeMethod(method: Method): Boolean` Determine whether the given method is a "finalize" method.
isHashCodeMethod	`open static fun isHashCodeMethod(method: Method): Boolean` Determine whether the given method is a "hashCode" method.
isJdkDynamicProxy	`open static fun isJdkDynamicProxy(object: Any): Boolean` Check whether the given object is a JDK dynamic proxy. This method goes beyond the implementation of `Proxy#isProxyClass(Class)` by additionally checking if the given object is an instance of SpringProxy.
isToStringMethod	`open static fun isToStringMethod(method: Method): Boolean` Determine whether the given method is a "toString" method.
selectInvocableMethod	`open static fun selectInvocableMethod(method: Method, targetType: Class<*>): Method` Select an invocable method on the target type: either the given method itself if actually exposed on the target type, or otherwise a corresponding method on one of the target type's interfaces or on the target type itself.
