| /** |
| * HandlingEvent |
| * |
| * A HandlingEvent is used to register the event when, for instance, |
| * a cargo is unloaded from a carrier at some location at a given time. |
| * |
| * The HandlingEvents are sent from different Incident Logging Applications |
| * some time after the event occurred and contain information about the |
| * {@link TrackingId}, {@link Location}, timestamp of the completion of the event, |
| * and possibly, if applicable a {@link Voyage}. |
| * |
| * Note that we don't save the whole cargo graph here as in the DDD sample! With |
| * the tracking id saved only, our HandlingEvent objects become much lighter and |
| * faster to save as we register incoming handling event data in high volumes from |
| * incident logging applications. |
| * |
| * HandlingEvents could contain information about a {@link Voyage} and if so, |
| * the event type must be either {@link HandlingEventType#LOAD} or |
| * {@link HandlingEventType#UNLOAD}. |
| * |
| * All other events must be of type {@link HandlingEventType#RECEIVE}, |
| * {@link HandlingEventType#CLAIM} or {@link HandlingEventType#CUSTOMS}. |
