Public Methods

public Advice getAdvice ()

Return the advice part of this aspect. An advice may be an interceptor, a before advice, a throws advice, etc.

Returns
  • the advice that should apply if the pointcut matches

public ClassFilter getClassFilter ()

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.

Returns
  • the class filter

public Class[] getInterfaces ()

Return the additional interfaces introduced by this Advisor or Advice.

Returns
  • the introduced interfaces

public boolean isPerInstance ()

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.

Returns
  • whether this advice is associated with a particular target instance

public void validateInterfaces ()

Can the advised interfaces be implemented by the introduction advice? Invoked before adding an IntroductionAdvisor.

Throws
IllegalArgumentException
