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