    • Method Detail

      • currentJoinPoint

        public static org.aspectj.lang.JoinPoint currentJoinPoint()
        Lazily instantiate joinpoint for the current invocation. Requires MethodInvocation to be bound with ExposeInvocationInterceptor.

        Do not use if access is available to the current ReflectiveMethodInvocation (in an around advice).

        current AspectJ joinpoint, or through an exception if we're not in a Spring AOP invocation.
      • getAspectJAdviceMethod

        public final java.lang.reflect.Method getAspectJAdviceMethod()
        Return the AspectJ-style advice method.
      • buildSafePointcut

        public final Pointcut buildSafePointcut()
        Build a 'safe' pointcut that excludes the AspectJ advice method itself.
        a composable pointcut that builds on the original AspectJ expression pointcut

      • getAspectInstanceFactory

        public final AspectInstanceFactory getAspectInstanceFactory()
        Return the factory for aspect instances.
      • getAspectClassLoader

        public final java.lang.ClassLoader getAspectClassLoader()
        Return the ClassLoader for aspect instances.
      • getOrder

        public int getOrder()
        Description copied from interface: Ordered
        Get the order value of this object.

        Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).

        Same order values will result in arbitrary sort positions for the affected objects.

        Specified by:
        getOrder in interface Ordered
        the order value
        See Also:
      • setAspectName

        public void setAspectName(java.lang.String name)
        Set the name of the aspect (bean) in which the advice was declared.
      • setDeclarationOrder

        public void setDeclarationOrder(int order)
        Set the declaration order of this advice within the aspect.
      • setArgumentNames

        public void setArgumentNames(java.lang.String argNames)
        Set by creator of this advice object if the argument names are known.

        This could be for example because they have been explicitly specified in XML, or in an advice annotation.

        argNames - comma delimited list of arg names
      • setArgumentNamesFromStringArray

        public void setArgumentNamesFromStringArray(java.lang.String... args)
      • setReturningName

        public void setReturningName(java.lang.String name)
      • setReturningNameNoCheck

        protected void setReturningNameNoCheck(java.lang.String name)
        We need to hold the returning name at this level for argument binding calculations, this method allows the afterReturning advice subclass to set the name.

        public void setThrowingName(java.lang.String name)
      • setThrowingNameNoCheck

        protected void setThrowingNameNoCheck(java.lang.String name)
        We need to hold the throwing name at this level for argument binding calculations, this method allows the afterThrowing advice subclass to set the name.
      • getDiscoveredThrowingType

        protected java.lang.Class<?> getDiscoveredThrowingType()
      • calculateArgumentBindings

        public final void calculateArgumentBindings()
        Do as much work as we can as part of the set-up so that argument binding on subsequent advice invocations can be as fast as possible.

        If the first argument is of type JoinPoint or ProceedingJoinPoint then we pass a JoinPoint in that position (ProceedingJoinPoint for around advice).

        If the first argument is of type JoinPoint.StaticPart then we pass a JoinPoint.StaticPart in that position.

        Remaining arguments have to be bound by pointcut evaluation at a given join point. We will get back a map from argument name to value. We need to calculate which advice parameter needs to be bound to which argument name. There are multiple strategies for determining this binding, which are arranged in a ChainOfResponsibility.
