Re: [aspectj-users] intercept exception and replace with return value (w

[Dean Wampler <dean@xxxxxxxxxxxxxxxxxxxxx>]

You have to use "around" advice to change the control flow. Something like this in your advice block:

try {

proceed (args);

} catch (ExceptionIWantToCatch e) {

do_recovery();

}

hi,

inside my code i would like to intercept an exception an replace it with a
return value? so my aspect is kind of a mediator which translates an
exception to a proper return value.
is this possible with aspectj?

something like:
@AfterThrowing(pointcut="call(@InterceptHandling *
aMethodCall(..))",throwing="exception")
public void replaceExceptionWithReturnValue(JoinPoint jp,Throwable
exception){          //handle exception
//create value and pass it as return value to method-callers
}

thanks for help.
