/**
 * {@code NamespaceHandler} for the {@code aop} namespace.
 *
 * 

Provides a {@link org.springframework.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 org.springframework.aop.Advisor} * and have it applied to all relevant beans in you {@link org.springframework.beans.factory.BeanFactory} * automatically. The {@code 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"/>
