                             java.lang.String typePattern,

Method Detail

getClassFilter

public ClassFilter getClassFilter()
Description copied from interface: IntroductionAdvisor
Return the filter determining which target classes this introduction should apply to.

This represents the class part of a pointcut. Note that method matching doesn't make sense to introductions.

Specified by:
getClassFilter in interface IntroductionAdvisor
Returns:
the class filter

validateInterfaces

public void validateInterfaces()
                        throws java.lang.IllegalArgumentException
Description copied from interface: IntroductionAdvisor
Can the advised interfaces be implemented by the introduction advice? Invoked before adding an IntroductionAdvisor.

Specified by:
validateInterfaces in interface IntroductionAdvisor
Throws:
java.lang.IllegalArgumentException - if the advised interfaces can't be implemented by the introduction advice

isPerInstance

public boolean isPerInstance()
Description copied from interface: Advisor
Return whether this advice is associated with a particular instance (for example, creating a mixin) or shared with all instances of the advised class obtained from the same Spring bean factory.

Note that this method is not currently used by the framework. Typical Advisor implementations always return true. Use singleton/prototype bean definitions or appropriate programmatic proxy creation to ensure that Advisors have the correct lifecycle model.

Specified by:
isPerInstance in interface Advisor
Returns:
whether this advice is associated with a particular target instance

getAdvice

public org.aopalliance.aop.Advice getAdvice()
Description copied from interface: Advisor
Return the advice part of this aspect. An advice may be an interceptor, a before advice, a throws advice, etc.

Specified by:
getAdvice in interface Advisor
Returns:
the advice that should apply if the pointcut matches
See Also:
MethodInterceptor, BeforeAdvice, ThrowsAdvice, AfterReturningAdvice

getInterfaces

public java.lang.Class[] getInterfaces()
Description copied from interface: IntroductionInfo
Return the additional interfaces introduced by this Advisor or Advice.

Specified by:
getInterfaces in interface IntroductionInfo
Returns:
the introduced interfaces
