/**
* NamespaceHandler for the aop namespace.
*
* Provides a {@link org.springframework.beans.factory.xml.BeanDefinitionParser} for the
* <aop:config> tag. A config tag can include nested
* pointcut, advisor and aspect tags.
*
*
The pointcut tag allows for creation of named
* {@link AspectJExpressionPointcut} beans using a simple syntax:
*
* <aop:pointcut id="getNameCalls" expression="execution(* *..ITestBean.getName(..))"/>
*
*
* Using the advisor tag you can configure an {@link org.springframework.aop.Advisor}
* and have it applied to all relevant beans in you {@link org.springframework.beans.factory.BeanFactory}
* automatically. The advisor tag supports both in-line and referenced
* {@link org.springframework.aop.Pointcut Pointcuts}:
*
*
* <aop:advisor id="getAgeAdvisor"
* pointcut="execution(* *..ITestBean.getAge(..))"
* advice-ref="getAgeCounter"/>
*
* <aop:advisor id="getNameAdvisor"
* pointcut-ref="getNameCalls"
* advice-ref="getNameCounter"/>
