  • 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

    • 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:

    • 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)

      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
