GeoPointRouteAttribute

Container that describes a point attribute of a route. Each item is stored as a point on the route, in which the item is located, and the value of the item itself.

Extends: Hashable
public static func == (lhs: GeoPointRouteAttribute, rhs: GeoPointRouteAttribute) -> Bool

Returns a Boolean value indicating whether two values are equal.

Methods
public func hash(into hasher: inout Hasher)

Hashes the essential components of this value by passing them to the given hasher.

Parameters
hasher
Hasher

Hasher to use when combining the components of this instance.

public func entries(
    begin: RoutePoint,
    end: RoutePoint
) -> [GeoPointRouteEntry]

Elements that fall within the [begin, end) range.

Parameters
begin
end
Returns
public func findNearBackward(
    point: RoutePoint
) -> GeoPointRouteEntry?

Finds the nearest element with position < = point.
The operation complexity is log2(N), where N = size.

Parameters
point
Returns
public func findNearForward(
    point: RoutePoint
) -> GeoPointRouteEntry?

Finds the nearest element with position < = point.
The operation complexity is log2(N), where N = size.

Parameters
point
Returns
public func calculateGeoPoint(
    routePoint: RoutePoint
) -> SegmentGeoPoint?

Calculates a GeoPoint from a known RoutePoint.
Operation complexity is O(log2(N)), where N = route_geometry.size()

Parameters
routePoint
Returns
SegmentGeoPoint?

Calculated geographic coordinates and direction of the segment pointed to by the route_point parameter. If the route is empty or route_point is out of range, nil is returned.

Properties
var size

Number of elements.

var isEmpty

Elements missing.

var first

First element.

var last

Last element.

var entries

All elements.

var length

Route length.
