The Delivery describes the actual transportation of the cargo, as opposed to the customer requirement {@link RouteSpecification} and the plan {@link Itinerary}. Complex data of the shipping domain is captured here in a value object that is re-created each time some delivery status changes. Booking The life cycle of a cargo begins with the booking procedure. During a (short) period of time, between booking and initial routing, the cargo has no itinerary and is therefore not_routed. Routing The booking clerk requests a list of possible routes, matching the route specification, and assigns the cargo to one route. The route to which a cargo is assigned is described by an itinerary. The cargo is now routed. Handling Receipt of the cargo in the origin location marks the beginning of a series of handling events that will eventually deliver the cargo at the destination. Handling events are supposed to be registered by local authorities and sent asynchronously to the cargo system which then re-calculate and replaces the delivery value object of the cargo. (In this implementation the trigger is synchronous in {@link ApplicationEvents}and the registration-ui is close to the booking and tracking interfaces for simplicity). Change of destination It may also happen that a cargo is accidentally misrouted when a new destination is selected in the middle of the voyage of the cargo. The cargo then becomes misrouted, which should notify the proper personnel and also trigger a re-routing procedure. In this implementation a synchronous message is sent to system output. Re-routing A cargo can be re-routed during transport, on demand of the customer, in which case a new route is specified for the cargo and a new route is requested. The old itinerary, being a value object, is discarded and a new one is attached to the cargo. Customs The cargo can be checked by the custom authorities anytime during the delivery. In that case it's unknown what happens next so the cargo is then considered misdirected. Claim The life cycle of a cargo ends when the cargo is claimed by the customer.
