All Implemented Interfaces:

IBackupElementConnector, Serializable

public class DefaultFlatEarthAverageSpeedBackupElementConnector
extends Object
implements IBackupElementConnector

The DefaultFlatEarthAverageSpeedBackupElementConnector is the default implementation used as IBackupElementConnector by the INodeEdgeConnector.

Constructor Detail

DefaultFlatEarthAverageSpeedBackupElementConnector

public DefaultFlatEarthAverageSpeedBackupElementConnector(boolean doRecalculateElement2ElementDuration)

Instantiates a new default flat earth average speed backup element connector. Every time a connection is extracted the driving time (duration) between two elements can be a function of the visitor. However, in case all visitors have the same average speed there is no recalculation necessary.

Parameters:

doRecalculateElement2ElementDuration - the do recalculate element 2 element duration

Method Detail

isRecalculateElement2ElementDuration

public boolean isRecalculateElement2ElementDuration()

Description copied from interface: IBackupElementConnector

Every time a connection is extracted the driving time (duration) between two elements can be a function of the visitors average speed. However, in case in which all visitors have the same average speed (or the difference is negligible) there is no recalculation necessary. However, in the final optimization result driving durations are presented with their actual average speeds.

Specified by:

isRecalculateElement2ElementDuration in interface IBackupElementConnector

Returns:

true, if is recalculate element-element duration

Using flat place on earth formula to calculate the distance between two IOptimizationElement.

Specified by:

getElement2ElementDistance in interface IBackupElementConnector

Parameters:

fromElementId - the string ID from the start element

fromElementLon - the double longitude from the start element

fromElementLat - the double latitude from the start element

toElementId - the string ID goal element

toElementLon - the double longitude from the target element

toElementLat - the double latitude from the target element

visitor - the iResource that is giving service to both Nodes on that Route

Returns:

the element too element distance
