Interface PointcutDesignatorHandler

public interface PointcutDesignatorHandler

The PointcutDesignator interface allows extension of the AspectJ pointcut language so that third-party tools integrating with AspectJ can add easily their own custom domain-specific designators and have them interoperate seamlessly with the standard AspectJ designators. A pointcut designator can only be used for matching, not for binding.
