    • DefaultIntroductionAdvisor

      public DefaultIntroductionAdvisor(Advice advice)
      Create a DefaultIntroductionAdvisor for the given advice.
      Parameters:
      advice - the Advice to apply (may implement the IntroductionInfo interface)
      See Also:

    • DefaultIntroductionAdvisor

      public DefaultIntroductionAdvisor(Advice advice, @Nullable IntroductionInfo introductionInfo)
      Create a DefaultIntroductionAdvisor for the given advice.
      Parameters:
      advice - the Advice to apply
      introductionInfo - the IntroductionInfo that describes the interface to introduce (may be null)

    • DefaultIntroductionAdvisor

      public DefaultIntroductionAdvisor(DynamicIntroductionAdvice advice, Class<?> ifc)
      Create a DefaultIntroductionAdvisor for the given advice.
      Parameters:
      advice - the Advice to apply
      ifc - the interface to introduce

  • Method Details

    • addInterface

      public void addInterface(Class<?> ifc)
      Add the specified interface to the list of interfaces to introduce.
      Parameters:
      ifc - the interface to introduce

    • getInterfaces

      public 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

    • 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

    • setOrder

      public void setOrder(int order)

    • getOrder

      public int getOrder()
      Description copied from interface: Ordered
      Get the order value of this object.

      Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).

      Same order values will result in arbitrary sort positions for the affected objects.

      Specified by:
      getOrder in interface Ordered
      Returns:
      the order value
      See Also:

    • getAdvice

      public 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:

    • 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

    • 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

    • matches

      public boolean matches(Class<?> clazz)
      Description copied from interface: ClassFilter
      Should the pointcut apply to the given interface or target class?
      Specified by:
      matches in interface ClassFilter
      Parameters:
      clazz - the candidate target class
      Returns:
      whether the advice should apply to the given target class

      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • toString

      public String toString()
