Description

A job to estimate the size of a tile cache to be exported from an ArcGIS Tile service.

Instances of this class represent a long running job on a remote server that can estimate the size of a tile cache to be exported from an ArcGIS Tile service.

A job is initiated when it is submitted to the server. See startWithStatusHandler:completion: (AGSEstimateTileCacheSizeJob).

When the server accepts the job, it assigns a unique ID to the job which is avialable in AGSJob::serverJobID. The client then periodically polls for the status of the job on the server and provides this information in the status handler. If the job completes successfully, the result of the job is provided in the completion handler, otherwise an error is provided when the job fails.

Method Documentation

◆ cancel

- (BOOL) cancel

Cancels the job. Returns a value indicating whether the job was successfully canceled.

Since: 100

Deprecated:: 100.1. Replaced by cancelWithCompletion:.

Provided by category AGSJob(AGSDeprecated).

◆ cancelWithCompletion:

- (id<AGSCancelable>) cancelWithCompletion: (void(^)(NSError *_Nullable error)) completion

Cancels this AGSJob and waits for any asynchronous, server-side operations to be canceled.

The job is canceled and will result in an AGSJobStatusFailed status after all cancellation tasks have completed. For jobs running on a server, a cancel request is sent for the associated AGSJob::serverJobID. You should always cancel unneeded jobs (for example when exiting your app) to avoid placing unnecessary load on the server. Examples of server-side jobs include:

In addition, the AGSGenerateOfflineMapJob is composed of several server-side jobs, depending on the types of layers in your AGSMap. Canceling this high-level job will also send a cancel request to the underlying server jobs.

Upon calling this method, the AGSJob::status is immediately set to AGSJobStatusCanceling.

Parameters

completion A block that is invoked when the operation completes successfully or encounters an error.

Returns: An operation which can be canceled.

Since: 100.14

◆ checkStatusWithCompletion:

- (id<AGSCancelable>) checkStatusWithCompletion: (void(^)(NSError *__nullable error)) completion

Force status check. This method can be called from UIApplication::application:performFetchWithCompletionHandler:.

Since: 100.0

◆ fromJSON:error:

+ (nullable id<AGSJSONSerializable>) fromJSON:	(id)	JSONObject
error:	(NSError **)	error

staticrequiredinherited

Initializes and returns an object from its JSON representation.

Parameters

JSONObject	`NSDictionary` or `NSArray` containing the JSON.
error	encountered during the operation, if any.

Since: 100

◆ pause

- (BOOL) pause

Pauses the job. Returns a value indicating whether the job was successfully paused.

Since: 100

Deprecated:: 100.1. Please use the pause method through the NSProgress API (exposed via NSProgressReporting through the progress property).

Provided by category AGSJob(AGSDeprecated).

◆ startWithStatusHandler:completion: [1/2]

- (void) startWithStatusHandler:	(nullable void(^)(AGSJobStatus status))	statusHandler
completion:	(void(^)(AGSEstimateTileCacheSizeResult __nullable result, NSError __nullable error))	completion

Start the job by submitting it to the server

Parameters

statusHandler	is invoked periodically whenever the job's status changes
completion	block that is invoked with the result when the job succeeds, or an error if it fails

Since: 100

◆ startWithStatusHandler:completion: [2/2]

- (void) startWithStatusHandler:	(nullable void(^)(AGSJobStatus status))	statusHandler
completion:	(void(^)(id __nullable result, NSError *__nullable error))	completion

◆ toJSON:

- (nullable id) toJSON: (NSError **) error

requiredinherited

Returns JSON representation for this object.

Parameters

error encountered during the operation, if any.

Returns: NSDictionary or NSArray containing the JSON.

Since: 100

Reimplemented in AGSPortalItem.

Property Documentation

◆ credential

- (AGSCredential*) credential

readwritenonatomicstronginherited

Security credentials to access the remote resource. Only applicable if the resource is secured.

Since: 100

◆ error

- (NSError*) error

readnonatomicstronginherited

Error encountered during job execution, if any.

Since: 100

◆ jobType

- (AGSJobType) jobType

readnonatomicassigninherited

The type of job

Since: 100

◆ messages

- (NSArray<AGSJobMessage*>*) messages

readnonatomiccopyinherited

Informational messages produced during execution of the job.

The messages can be monitored using Key-Value Observing (KVO).

Since: 100

◆ progress

- (NSProgress*) progress

readnonatomicstronginherited

The progress for this job. As a consumer of this progress property, you can observe it's property changes and pause, cancel, resume. Do not, however, set the readwrite properties of this progress object. Those are reserved for internal use. Setting them externally will corrupt the state and lead to undefined behavior.

Since: 100.1

◆ requestConfiguration

- (AGSRequestConfiguration*) requestConfiguration

readwritenonatomicstronginherited

The AGSRequestConfiguration object which defines the behavior and policies to use when accessing the remote resource. The default will be nil. If it is nil the [AGSRequestConfiguration globalConfiguration] will be used.

Since: 100

◆ result

- (AGSEstimateTileCacheSizeResult*) result

readnonatomicstrong

Result of the job.

Since: 100

◆ serverJobID

- (NSString*) serverJobID

readnonatomiccopyinherited

Unique ID of the job on the server on which it is executing.

Since: 100

◆ status

- (AGSJobStatus) status

readnonatomicassigninherited

Current status of the job.

The status can be monitored using Key-Value Observing (KVO).

Since: 100

◆ unknownJSON

- (NSDictionary<NSString*,id>*) unknownJSON

readrequirednonatomiccopyinherited

A dictionary of values that was in the source JSON but was unparsed by API.

Returns: NSDictionary containing the unknown JSON.

Since: 100

◆ unsupportedJSON

- (NSDictionary<NSString*,id>*) unsupportedJSON

readnonatomiccopyinherited

A dictionary of values that are supported by the REST API, but not exposed through the SDK API.

Returns: NSDictionary containing the unsupported JSON.
