Description copied from interface: IGISRouteFinder

Returns the distance by route with intermediate points.

Parameters:: latLonPoints - the array of coordinates ([latitude1, longitude1, latitude2, longitude2, ... latitudeN, longitudeN])
Returns:: the distance of route which sequentially connects all specified points, empty optional if route not found, or null in case of server error

getRoute

public GISResult<double[]> getRoute(double[] latLonPoints)

Description copied from class: AbstractGISRouteFinder

Returns curve obtained "as is" from route provider, without generalization

Specified by:: getRoute in interface IGISRouteFinder
Specified by:: getRoute in class AbstractGISRouteFinder
Parameters:: latLonPoints - (lat, lon) pairs representing, the start, then optional intermediate, and the end points. Returns array of (lat, lon) pairs of resulting route curve, after all the points there is a number with the total distance.
Returns:: see above, or empty optional if route not found, or null in case of server error
