AGSSyncGeodatabaseJob Class Reference

Description

A job to synchronize changes between a geodatabase and an ArcGIS Feature service.

Instances of this class represent a long running job on a remote server that can synchronize changes between a geodatabase and an ArcGIS Feature service.

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

When the server accepts the job, it assigns a unique ID to the job which is avialable in 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.

License Restrictions:
This feature requires a Basic license for production deployment when sync direction is Bidirectional or Upload with public feature services or when using a private feature service with any sync direction. "Public" feature services means services hosted on the Internet and available anonymously (not secured). "Private" includes all other scenarios such as feature services hosted on a local network within an enterprise or feature services hosted on the Internet but secured . No license required in Developer mode for testing.

Method Documentation

◆ cancel

- (BOOL) cancel

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

Since
100
Deprecated:
100.1. Please use the cancel method through the NSProgress API (exposed via NSProgressReporting through the progress property).

◆ 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
JSONObjectNSDictionary or NSArray containing the JSON.
errorencountered 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).

◆ startWithStatusHandler:completion: [1/2]

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

◆ startWithStatusHandler:completion: [2/2]

- (void) startWithStatusHandler: (nullable void(^)(AGSJobStatus status))  statusHandler
completion: (void(^)(NSArray< AGSSyncLayerResult * > *__nullable result, NSError *__nullable error))  completion 

Start the job by submitting it to the server

Parameters
statusHandleris invoked periodically whenever the job's status changes
completionblock that is invoked with the result when the job succeeds, or an error if it fails
Note
The result array only contains entries for layers or tables that encountered edit errors during the sync process. If all edits of a layer or table could be synchronized without errors, it is not included in the result array. Also, if the entire sync operation failed, for example due to network interruption, the result array is nil, and the error argument is populated instead.

◆ toJSON:

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

Returns JSON representation for this object.

Parameters
errorencountered during the operation, if any.
Returns
NSDictionary or NSArray containing the JSON.
Since

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

◆ geodatabaseDeltaInfo

- (AGSGeodatabaseDeltaInfo*) geodatabaseDeltaInfo
readnonatomicstrong

Returns information on geodatabase upload and download delta files.

When AGSSyncGeodatabaseParameters::keepGeodatabaseDeltas is set to YES, this property provides information about the synced geodatabase along with the paths to its uploaded and downloaded deltas.

Delta geodatabases allow you to troubleshoot sync problems - for example by inspecting the changes they contain or sending the file to the system administrator for the feature service.

This property will be set even if the job fails. If AGSSyncGeodatabaseParameters::keepGeodatabaseDeltas is NO, this property will be nil.

Since
100.10

◆ jobType

- (AGSJobType) jobType
readnonatomicassigninherited

The type of job

Since
100

◆ messages

- (NSArray<AGSJobMessage*>*) messages
readnonatomiccopyinherited

Informational messages produced during execution of the job.

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

- (NSArray<AGSSyncLayerResult*>*) result
readnonatomicstrong

For a successfully completed job, an array of AGSSyncLayerResult is returned. If all edits to the geodatabase's tables and layers are synced successfully, an empty array is returned.

If the job did not succeed, a nil result array is returned.

If the job succeeded, but individual edits failed to sync, the result array provides an array of each failed edit operation (AGSFeatureEditResult) grouped by the geodatabase table name. Only errors are reported.

If the array is empty, it should be assumed all edits were synchronized properly and no edit errors were encountered during the sync process.

Since
100

◆ serverJobID

- (NSString*) serverJobID
readnonatomiccopyinherited

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