public Interceptor getInterceptor(Advisor advisor)

Don't worry about any Pointcut contained in the Advisor; the AOP framework will take care of checking the pointcut.

Specified by:

getInterceptor in interface AdvisorAdapter

Parameters:

advisor - the Advisor. The supportsAdvice() method must have returned true on this object
