| /** |
| * RouteSpecification |
| * |
| * Describes: |
| * - where a cargo is going from (origin) |
| * - the earliest departure date from origin (earliestDeparture) |
| * - where a cargo is going to (destination) |
| * - when a cargo is expected to arrive (arrivalDeadline) |
| * |
| * If the route specification needs to change because of unexpected |
| * handling events, it's replaced with a new one in {@link Cargo}. |
| * |
| * An itinerary describes the route a cargo can take, and it satisfies the route |
| * specification when the route |
| * - starts in the origin location of the route specification origin |
| * - starts after the earliest departure of the route specification |
| * - ends in the destination location of the route specification |
| * - ends before the arrival deadline of the route specification |
| * |
| * DCI Data is supposed to be dumb. Can we accept to have the specification |
| * logic here? |
| * |
| * All properties are mandatory and immutable. |
