Constructor Detail

DeclareParentsAdvisor

public DeclareParentsAdvisor(Class interfaceType,
                             String typePattern,
                             Class defaultImpl)

Create a new advisor for this DeclareParents field.

Parameters:: interfaceType - static field defining the introduction; typePattern - type pattern the introduction is restricted to; defaultImpl - default implementation class

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 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:: 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 Advice getAdvice()
