Class NodeEdgeConnector

java.lang.Object
com.dna.jopt.member.unit.nodeedge.AbstractNodeEdgeConnector
com.dna.jopt.member.unit.nodeedge.NodeEdgeConnector
All Implemented Interfaces:
INodeEdgeConnector, Serializable
public class NodeEdgeConnector extends AbstractNodeEdgeConnector
A node connector is holding a table of INodeConnectorItem which hold the two Strings of the start and the end location. Each INodeConnectorItem is describing for example the time, distance etc. between two nodes.

The INodeConnectorItem can be populated with realistic data on distance and time needed between two locations. The time and distance between two locations can be different depending in which direction you are heading since traffic or route taken might change. If not populated, air distance and average speed is being used.

The Nodes are filtered before the INodeconnector is being populated. If one Node is only accessible in December and another one only in January the Optimizer never puts them in the same Route and the specific data on the distance between these Nodes does not need to be acquired.

Implementation example: 


 List<INodeConnectorItem> connectionItems = new ArrayList<INodeConnectorItem>();

   // Add connections from resources

     INodeConnectorItem connectionJackHeilbronn = new NodeEdgeConnectorItem();
     connectionJackHeilbronn.setFromOptimizationElement(resourceJackHeilbronn);
     connectionJackHeilbronn.setToOptimizationElement(cityHeilbronn);
     connectionJackHeilbronn.setDistance(Quantities.getQuantity(2, KILO(METRE)));
     connectionJackHeilbronn.setDrivingTime(Duration.ofMinutes(10));
     connectionItems.add(connectionJackHeilbronn);

   // Add some connection items => The rest will be generated as fall back solution to bird
   // distances.

     INodeConnectorItem connectionKoelnOberhausen = new NodeEdgeConnectorItem();
     connectionKoelnOberhausen.setFromOptimizationElement(cityKoeln);
     connectionKoelnOberhausen.setToOptimizationElement(cityOberhausen);
     connectionJackHeilbronn.setDistance(Quantities.getQuantity(20, KILO(METRE)));
     connectionKoelnOberhausen.doAutoCalculateTime(true); // The time will be calculated based on the provided distance
     connectionItems.add(connectionKoelnOberhausen);

      INodeConnectorItem connectionOberhausenKoeln = new NodeEdgeConnectorItem();
     connectionOberhausenKoeln.setFromOptimizationElement(cityOberhausen);
     connectionOberhausenKoeln.setToOptimizationElement(cityKoeln);
     connectionJackHeilbronn.setDistance(Quantities.getQuantity(20, KILO(METRE)));
     connectionOberhausenKoeln.doAutoCalculateTime( true); // The time will be calculated based on the provided distance
     connectionItems.add(connectionOberhausenKoeln);

     INodeEdgeConnector myNodeConnector = new NodeEdgeConnector();

   // Add items to connector
     myNodeConnector.putNodeConnections(connectionItems);

   // Set NodeEdgeConnector
     setNodeConnector(this.myNodeConnector);
