GeoPointRouteAttribute

Container that describes a point attribute of a route. Each element is stored as the point on the route (where the element is located) and the value of the element itself.

Extends: ru.dgis.sdk.NativeObject
Methods
fun entries(begin: RoutePoint, end: RoutePoint): List<GeoPointRouteEntry>

Elements falling within the [begin, end) range.

Parameters
begin
end
Returns
fun findNearBackward(point: RoutePoint): GeoPointRouteEntry?

Finds the nearest element the position of which is < = point.

The complexity of the operation is log2(N), where N = size.

Parameters
point
Returns
fun findNearForward(point: RoutePoint): GeoPointRouteEntry?

Finds the nearest element the position of which is < = point.

The complexity of the operation is log2(N), where N = size.

Parameters
point
Returns
fun calculateGeoPoint(routePoint: RoutePoint): SegmentGeoPoint?

Calculates a GeoPoint from a known RoutePoint.

Parameters
routePoint
Returns
SegmentGeoPoint?

Calculated geographical coordinates and the direction of the segment pointed to by the route_point parameter. If the route is empty or the route_point goes beyond the route, null is returned.

The complexity of the operation is O(log2(N)), where N = route_geometry .size()

fun calculateClosestPoint(point: GeoPoint): RoutePoint?

Calculates the nearest point on the route to the given geographic coordinates of a point.

Parameters
point
GeoPoint

Point projected on the route.

Returns
RoutePoint?

Nearest point on the route. If the route is empty of both range.first and range.second points are located before of after the route, null is returned.

Operation complexity is O(N), where N = route_geometry.size()
