public class AspectJExpressionPointcut extends AbstractExpressionPointcut implements ClassFilter, IntroductionAwareMethodMatcher, BeanFactoryAware
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.
TRUE

isRuntime()
Is this MethodMatcher dynamic, that is, must a final call be made on the
MethodMatcher.matches(java.lang.reflect.Method, Class, Object[]) method at
runtime even if the 2-arg matches method returns true ? |
boolean |
matches(java.lang.Class<?> targetClass)
Should the pointcut apply to the given interface or target class?
|
boolean |
matches(java.lang.reflect.Method method,
java.lang.Class<?> targetClass)
Perform static checking whether the given method matches.
|
boolean |
matches(java.lang.reflect.Method method,
java.lang.Class<?> targetClass,
boolean beanHasIntroductions)
Perform static checking whether the given method matches.
|
boolean |
matches(java.lang.reflect.Method method,
java.lang.Class<?> targetClass,
java.lang.Object... args)
Check whether there a runtime (dynamic) match for this method,
which must have matched statically.

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