All Implemented Interfaces:

HasId, HasIndex, Job

public class Shipment
extends AbstractJob

Shipment is an implementation of Job and consists of a pickup and a delivery of something.

It distinguishes itself from Service as two locations are involved a pickup where usually something is loaded to the transport unit and a delivery where something is unloaded.

By default serviceTimes of both pickup and delivery is 0.0 and timeWindows of both is [0.0, Double.MAX_VALUE],

A shipment can be built with a builder. You can get an instance of the builder by coding Shipment.Builder.newInstance(...). This way you can specify the shipment. Once you build the shipment, it is immutable, i.e. fields/attributes cannot be changed anymore and you can only 'get' the specified values.

Note that two shipments are equal if they have the same id.
