    - #### DeclareParentsAdvisor

          public DeclareParentsAdvisor(Class<?> interfaceType,
                                       String typePattern,
                                       Class<?> defaultImpl)

      Create a new advisor for this DeclareParents field.
      参数:
        `interfaceType` - static field defining the introduction
        `typePattern` - type pattern the introduction is restricted to
        `defaultImpl` - the default implementation class

    - #### DeclareParentsAdvisor

          public DeclareParentsAdvisor(Class<?> interfaceType,
                                       String typePattern,
                                       Object delegateRef)

      Create a new advisor for this DeclareParents field.
      参数:
        `interfaceType` - static field defining the introduction
        `typePattern` - type pattern the introduction is restricted to
        `delegateRef` - the delegate implementation object

  - ### 方法详细资料

    - #### getClassFilter

          public ClassFilter getClassFilter()

      从接口复制的说明: `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.

      指定者:
        `getClassFilter` 在接口中 `IntroductionAdvisor`
      返回:
        the class filter

    - #### validateInterfaces

          public void validateInterfaces()
                                  throws IllegalArgumentException

      从接口复制的说明: `IntroductionAdvisor`
      Can the advised interfaces be implemented by the introduction advice? Invoked before adding an IntroductionAdvisor.
      指定者:
        `validateInterfaces` 在接口中 `IntroductionAdvisor`
      抛出:
        `IllegalArgumentException` - if the advised interfaces can't be implemented by the introduction advice

    - #### isPerInstance

          public boolean isPerInstance()

      从接口复制的说明: `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.

      指定者:
        `isPerInstance` 在接口中 `Advisor`
      返回:
        whether this advice is associated with a particular target instance

    - #### getAdvice

          public Advice getAdvice()

      从接口复制的说明: `Advisor`
      Return the advice part of this aspect. An advice may be an interceptor, a before advice, a throws advice, etc.
      指定者:
        `getAdvice` 在接口中 `Advisor`
      返回:
        the advice that should apply if the pointcut matches
      另请参阅:
        `MethodInterceptor`, `BeforeAdvice`, `ThrowsAdvice`, `AfterReturningAdvice`

    - #### getInterfaces

          public Class<?>[] getInterfaces()

      从接口复制的说明: `IntroductionInfo`
      Return the additional interfaces introduced by this Advisor or Advice.
      指定者:
        `getInterfaces` 在接口中 `IntroductionInfo`
      返回:
        the introduced interfaces
