Is it possible to intercept method in Abstract Class

nizzy Feb 5, 2010 7:29 AM

Hi All,

Is it possible to intercept a method in an Abstract Class?

I have tried;

     <bind pointcut="execution(protected * xxx.xxx.AbstractHandler->aquireHandler(..))">
          <interceptor-ref name="mockhandler"/>
     </bind>

     <bind pointcut="execution(protected abstract * xxx.xxx.AbstractHandler->aquireHandler())">
     <interceptor-ref name="mockhandler"/>
     </bind>

     <bind pointcut="execution(protected * xxx.xxx.ConcreteHandler->aquireHandler())">
     <interceptor-ref name="mockhandler"/>
     </bind>

We weave the point where the method is actually implemented by replacing the method body, so try

<bind pointcut="execution(protected * $instanceof{xxx.xxx.AbstractHandler}->aquireHandler(..)})"> <interceptor-ref name="mockhandler"/> </bind>
This is assuming that aquireHandler is an abstract method

Hi Kabir,

The class is abstract but the method is common to all sub-classes and so is implemented in abstract class.

Thanks again for the help I can now intercept using pointcut;

<bind pointcut="execution(protected * $instanceof{*.AbstractHandler}->aquireHandler(..))"> <interceptor-ref name="mockhandler"/> </bind>

Which is pretty much exactly as you suggested Kabir, cheers.
