Inspect Cargo Delivery Status (subfunction use case) Third and last step in the ProcessHandlingEvent use case. Updates our knowledge about a cargo delivery. All we know about the delivery is saved in a Delivery value object that is replaced each time it's updated. Cargo is playing the Role of a Delivery Inspector that inspects a specific handling event in order to update the Delivery status for the cargo. If the Delivery Inspector realizes that the cargo is not on track, proper notifications are sent out so that the cargo owner can re-route the cargo or the system take some action. Handling cargo in customs is a completely different process and context than loading it onto a ship, so each handling event has its own use case and thus its own Context. Each of those (sub-)subfunction use cases/Contexts reflects our understanding of a real world process and can be easily reviewed, maintained, specialized, tested etc. It's now easy to understand what our program does and what we can expect from it - basically in one place in the code.


        public void inspect( HandlingEvent handlingEvent )
        {
            try
            {
                new InspectCargoDeliveryStatus( handlingEvent ).update();
                logger.info( "Inspected handled cargo '" + handlingEvent.trackingId().get().id().get() + "'." );
            }
            catch( InspectionFailedException e )
            {
                logger.error( e.getMessage() ); // Unexpected error


                cargo.routeSpecification().set( newRouteSpec );


                // Step 4 - Update cargo delivery status


                new InspectCargoDeliveryStatus( cargo ).update();
            }
