Description

A task to compute routes and turn-by-turn directions.

Instances of this class represent a task used to compute routes and turn-by-turn directions. It allows you to find a variety of routes between any given locations - the quickest, shortest, most scenic, and so on. The route returned depends on the impedance chosen by you. For example, if the impedance is time, then the best route is the quickest route. Hence, the best route can be defined as the route that has the lowest impedance.

The task can be created for an ArcGIS Network Analyst service hosted in the cloud on ArcGIS Online or on-premises with ArcGIS Server. The task can also be created for a transportation network dataset stored locally on the device in which case it can used even when the device has no network connectivity.

Method Documentation

§ cancelLoad()

- (void) cancelLoad

requiredinherited

Cancels loading if it is in progress, otherwise it does nothing. This should be called carefully because other objects could be waiting for loadWithCompletion: or retryLoadWithCompletion: to complete and this will call them all back with the error of NSUserCancelledError

Since: 100

§ defaultRouteParametersWithCompletion:()

- (id<AGSCancelable>) defaultRouteParametersWithCompletion: (void(^)(AGSRouteParameters *__nullable routeParams, NSError *__nullable error)) completion

A convenience method to get properly initialized parameters for computing a route. The parameters are initialized with default values based on the routeTaskInfo

Parameters

completion block that is invoked when the operation completes. The route parameters are populated if the operation succeeds, else the error is populated if the operation fails.

Since: 100

§ initWithDatabaseName:networkName:()

- (instancetype) initWithDatabaseName:	(NSString *)	databaseName
networkName:	(NSString *)	networkName

Initialize the task with the name of a geodatabase containing a transportation network dataset, and the name of the dataset.

Parameters

databaseName	name of the geodatabase file (within the application bundle or shared documents directory) without the .geodatabase file extension
networkName	name of the transportation network dataset within the geodatabase

Returns: a new route task

Since: 100

§ initWithDataset:()

- (instancetype) initWithDataset: (AGSTransportationNetworkDataset *) dataset

Initialize the task with a reference to the transportation network dataset available for a map.

Parameters

dataset transportation network dataset to use

Returns: a new route task

Since: 100

See also: AGSMap::transportationNetworks to get a reference to the transportation network datasets available for a map.

§ initWithFileURLToDatabase:networkName:()

- (instancetype) initWithFileURLToDatabase:	(NSURL *)	fileURLToDatabase
networkName:	(NSString *)	networkName

Initialize the task with a path to the geodatabase containing a transportation network dataset, and the name of the transportation network dataset.

Parameters

fileURLToDatabase	URL to the .geodatabase file on disk
networkName	name of the transportation network dataset within the geodatabase

Returns: a new route task

Since: 100

§ initWithURL:()

- (instancetype) initWithURL: (NSURL *) URL

Initialize the task with a URL to a route layer in an ArcGIS Network Analyst service. The service may be hosted in the cloud on ArcGIS Online or on-premises with ArcGIS Server.

Parameters

URL	to a route layer in an ArcGIS Network Analyst service. For example, http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Network/USA/NAServer/Route

Returns: a new route task

Since: 100

§ loadWithCompletion:()

- (void) loadWithCompletion: (nullable void(^)(NSError *__nullable error)) completion

requiredinherited

Loads data for the object asynchronously. The completion block is invoked upon completion.

You can call this method any number of times, however only one attempt is made to load the data. If it is already loading, it will just continue to load (i.e. not force a reload). If it has already loaded successfully, the completion block will be invoked right away. If it has already failed to load, the completion block will be invoked right away with error previously encountered. This method supports multiple callers and will call them all back on completion. However, each caller's completion block will be invoked once and only once.

Parameters

completion block that is invoked when object loads successfully or fails to load. An error is passed to the block if the object fails to load.

Note: The completion block is always invoked on the main thread.

Since: 100

See also: - cancelLoad to cancel loading; - retryLoadWithCompletion: to force reload

§ retryLoadWithCompletion:()

- (void) retryLoadWithCompletion: (nullable void(^)(NSError *__nullable error)) completion

requiredinherited

Tries to reload when an object has failed to load. This method should be called judiciously. It should be called when:

you didn't have network connectivity earlier when it failed and you want to retry now that you have connectivity
the server was down earlier when it failed and you want to retry
the request is taking too long and you want to cancel it and retry, in which case you will first call cancelLoad and then this method

If the data hasn't started loading, it will start loading. If it is already loading, it will just continue to load. If it has already loaded successfully, calls back right away. If it has already failed to load, tries again. This method supports multiple callers and will call them all back on completion. However, each caller's completion block will be invoked once and only once.

Parameters

completion block that is invoked when object loads successfully or fails to load. An error is passed to the block if the object fails to load.

Note: The completion block is always invoked on the main thread.

§ routeParametersWithFeatureCollection:completion:()

- (id<AGSCancelable>) routeParametersWithFeatureCollection:	(AGSFeatureCollection *)	featureCollection
completion:	(void(^)(AGSRouteParameters __nullable routeParams, NSError __nullable error))	completion

A convenience method to get properly initialized parameters for computing a route. The parameters are initialized with default values based on the routeTaskInfo, and every feature in the provided feature collection is added as a stop along the desired route.

Parameters

featureCollection	containing the stops
completion	block that is invoked when the operation completes. The route parameters are populated if the operation succeeds, else the error is populated if the operation fails.

A convenience method to get properly initialized parameters for computing a route similar to the one in the portal item. The item's type must be AGSPortalItemTypeFeatureCollection and the item must represent a route layer (i.e the item's typeKeywords must contain "Route Layer"). The parameters are initialized with default values based on the routeTaskInfo, and every feature in the provided feature collection is added as a stop along the desired route.

Parameters

portalItem	representing a feature collection that contains stops, route info, and barriers tables. Stops table is required.
completion	block that is invoked when the operation completes. The route parameters are populated if the operation succeeds, else the error is populated if the operation fails.
