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

RoutePoint

end

RoutePoint

Returns

GeoPointRouteEntry[]

public func findNearBackward(
    point: RoutePoint
) -> GeoPointRouteEntry?

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

Parameters

point

RoutePoint

Returns

GeoPointRouteEntry?

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

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

Parameters

point

RoutePoint

Returns

GeoPointRouteEntry?

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

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.

public func calculateClosestPoint(
    point: GeoPoint
) -> RoutePoint?

Calculates the nearest point on the route to the given geographic coordinates of a point.
Operation complexity is O(N), where N = route_geometry.size()

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, nil is returned.

Properties

var size

UInt64

Number of elements.
