A RoutingStrategy that calculates the shortest route between RouteStops.
Inheritance HierarchyNamespace: Telogis.GeoBase.Routing
Assembly: geobase.net (in geobase.net.dll) Version: 4.99.0.0
SyntaxThe RoutingStrategyShortest type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | RoutingStrategyShortest | Initializes a new instance of the RoutingStrategyShortest class |
Properties| Name | Description | |
|---|---|---|
 | AllowUTurns |
When true, allows the routing engine to instruct a u-turn. When false, generated
routes will not contain u-turns if possible. Default is true.
(Inherited from RoutingStrategy.) |
| CostUnits |
Gets the units in which the cost for this strategy is calculated in (always returns meters).
(Overrides RoutingStrategyCostUnits.) |
| CustomCostFunction |
Gets or sets a custom function used to adjust the cost associated with a particular link.
(Inherited from RoutingStrategy.) |
| CustomRoutingAccessKeys |
Gets or sets the custom routing access keys for this route.
(Inherited from RoutingStrategy.) |
| DefaultProfile | Obsolete.
The default RoutingProfile for
all countries. This profile will be overridden if a profile has been set for another country.
(Inherited from RoutingStrategy.) |
| EnhanceRoute |
When true, routing will consider more minor streets close to the direct line between two
consecutive route stops. This is likely to improve the quality of shortest routes, but at
the price of some impact on performance and memory usage.
|
| ExtraProcessingRatio |
Used to increase the area of the bounding boxes for querying the network.
(Inherited from RoutingStrategy.) |
| IgnoreConstraints |
When true, tells the routing engine to ignore all constraints. When false (default), constraints are obeyed.
(Inherited from RoutingStrategy.) |
| IgnoreDrivingDirection |
When true, tells the routing engine to ignore the direction of one way roads.
Default is false.
(Inherited from RoutingStrategy.) |
| KeepOut |
Sets a GeoFence area where the router will
not send vehicles. You can use this to keep the route from going through a specific
area.
(Inherited from RoutingStrategy.) |
| KeyAccessPredicate |
Gets or sets a custom predicate used to instruct the routing engine whether an access constraint may be ignored.
(Inherited from RoutingStrategy.) |
 | LinkEdits |
A set of link edits that, for selected links, will override the default speed that is
used when calculating a route.
(Inherited from RoutingStrategy.) |
| ObeyPreferredConstraints |
When true, tells the routing engine to use preferred constraints. May introduce a performance penalty.
When false (default), preferred constraints are not obeyed.
(Inherited from RoutingStrategy.) |
| RoadCrossingBehavior |
Sets the permitted type of road crossing behavior (Allowed, Discouraged, Forbidden).
(Inherited from RoutingStrategy.) |
| UseFerries |
Sets whether ferry crossings are allowed (true) or should be avoided as much as possible (false).
Default is true.
(Inherited from RoutingStrategy.) |
| UseTollRoads |
Gets or sets whether this route is allowed to use toll roads. Default is true.
(Inherited from RoutingStrategy.) |
Methods| Name | Description | |
|---|---|---|
| CalculateTimeAfter |
Calculates the time after passing through the link.
(Inherited from RoutingStrategy.) |
| Dispose |
Frees all (managed & unmanaged) resources associated with this RoutingStrategy.
(Overrides RoutingStrategyDispose.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetAllowedVehicleTypes |
Returns the types of vehicles that are allowed on a particular functional class road on this strategy.
(Inherited from RoutingStrategy.) |
| GetHashCode |
Returns a unique integer for this object.
(Inherited from RoutingStrategy.) |
| GetProfile |
Gets the RoutingProfile
for a certain country for this RoutingStrategy.
(Inherited from RoutingStrategy.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| RegisterProfile |
Registers the RoutingProfile for
a given country and type of vehicle.
(Inherited from RoutingStrategy.) |
| SetAllowedVehicleTypes |
Sets the types of vehicles that are allowed on a particular functional class road on this strategy.
(Inherited from RoutingStrategy.) |
| SetProfile(RoutingProfile) | Obsolete. (Inherited from RoutingStrategy.) |
| SetProfile(Country, RoutingProfile) |
Sets the RoutingProfile
for a certain country.
(Inherited from RoutingStrategy.) |
| SetProfile(Country, RoutingProfile) |
Sets the RoutingProfile for all the countries
in an array.
(Inherited from RoutingStrategy.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| ToXml |
Used to serialize a RoutingStrategy
object to XML.
(Inherited from RoutingStrategy.) |

Examples
This strategy will attempt to minimize the distance traveled on the route, even
if this means increasing the driving time (by, for example, taking
surface streets and avoiding highways).
C#
// Create a Route. Route ShortRoute = new Route(); // Change the Route Strategy. Determine the shortest route. ShortRoute.Strategy = new RoutingStrategyShortest();
