Examples of jsprit.core.problem.job.Service

jsprit.core.problem.job.Service
Service implementation of a job.
A service distinguishes itself from a shipment such that it has only one location. Thus a service is a single point in space (where a service-activity occurs).
Note that two services are equal if they have the same id. @author schroeder
