Class TransportStartComparator

java.lang.Object

org.openwms.tms.impl.state.TransportStartComparator

All Implemented Interfaces:

Serializable, Comparator<TransportOrder>

class TransportStartComparator
extends Object
implements Comparator<TransportOrder>, Serializable

A TransportStartComparator. I used to sort TransportOrders is a particular order. Unfortunately some fields of the TransportOrder class are defined as Enums for a better handling in business logic. Persisting these fields as Strings makes it impossible to do a proper sorting in the database with JPA. Hence we must do it with Comparators in the application layer.
