java.lang.Object org.springframework.aop.support.AbstractExpressionPointcut org.springframework.aop.aspectj.AspectJExpressionPointcut
public class AspectJExpressionPointcut
Spring Pointcut
implementation
that uses the AspectJ weaver to evaluate a pointcut expression.
The pointcut expression value is an AspectJ expression. This can reference other pointcuts and use composition and other operations.
Naturally, as this is to be processed by Spring AOP's proxy-based model, only method execution pointcuts are supported.

Perform static checking whether the given method matches. |
boolean |
matches(Method method,
Class targetClass,
boolean beanHasIntroductions)
Perform static checking whether the given method matches. |
boolean |
matches(Method method,
Class targetClass,
Object[] args)
Check whether there a runtime (dynamic) match for this method, which must have matched statically. |

immediately before potential running of the advice, after any
advice earlier in the advice chain has run.
