AGSArcGISFeatureTable Class Reference

Description

An ArcGIS specific source for dataset containing geographic features or non-spatial records.

Subclasses represent an ArcGIS-specific source for dataset that could include either geographic features or non-spatial records. You can query the dataset using attribute or spatial criteria, and if permitted, also edit the data. Edits are tracked, so you can later retrieve a list of edits. If the dataset contains geographic features you can display them on a map using AGSFeatureLayer.

◆ doCancelLoading

- (void) doCancelLoading

Never call this method directly. The framework calls this method on a background thread when cancelLoad (AGSLoadable-p) is called. It is meant to be overriden by subclasses. Subclasses should override this method to cancel loading their data and call loadDidFinishWithError: (AGSLoadableBase(ForSubclassEyesOnly)) at the end passing in an error representing NSUserCancelledError.

Since
100

Provided by category AGSLoadableBase(ForSubclassEyesOnly).

◆ doStartLoading:

- (void) doStartLoading: (BOOL)  retrying

Never call this method directly. The framework calls this method on a background thread when loadWithCompletion: (AGSLoadable-p) or retryLoadWithCompletion: (AGSLoadable-p) is called. It is meant to be overriden by subclasses. Subclasses should override this method to load their data and call loadDidFinishWithError: (AGSLoadableBase(ForSubclassEyesOnly)) upon completion, passing in the error if any.

Parameters
retryingflag that is true if this method was called from retryLoadWithCompletion: (AGSLoadable-p).
Since
100

Provided by category AGSLoadableBase(ForSubclassEyesOnly).

◆ featureTemplateForName:

- (nullable AGSFeatureTemplate *) featureTemplateForName: (NSString *)  name

Convenience method to getting a field object given its name

Parameters
fieldNameThe name of the field.
Returns
field
Since
100

◆ hasLocalEdits

- (BOOL) hasLocalEdits

Checks whether the feature table has local edits.

For AGSServiceFeatureTable, local edits are edits that have not yet been applied to the feature service. For AGSGeodatabaseFeatureTable, local edits are edits that have been made since the last acknowledged upload.

Returns
Whether the table has local edits.
Since
100.9

◆ loadDidFinishWithError:

- (void) loadDidFinishWithError: (nullable NSError *)  error

Only subclasses should call this method in doStartLoading: (AGSLoadableBase(ForSubclassEyesOnly)) and doCancelLoading (AGSLoadableBase(ForSubclassEyesOnly)) when done loading or failed to load.

Since
100

Provided by category AGSLoadableBase(ForSubclassEyesOnly).

◆ 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
completionblock 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

- cancelLoad to cancel loading
- retryLoadWithCompletion: to force reload

◆ onLoadStatusChanged

- (void) onLoadStatusChanged

Never call this method directly. The framework calls this method on a background thread when AGSLoadable::loadStatus changes is called. Subclasses can optionally implement this to know when their loading status has changed.

Since
100

Provided by category AGSLoadableBase(ForSubclassEyesOnly).

Since
100.1

◆ 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:

  1. you didn't have network connectivity earlier when it failed and you want to retry now that you have connectivity
  2. the server was down earlier when it failed and you want to retry
  3. 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
completionblock 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

◆ updatedFeaturesCountWithCompletion:

- (id<AGSCancelable>) updatedFeaturesCountWithCompletion: (void(^)(NSInteger count, NSError *__nullable error))  completion

Parameters
completionA block that is invoked when the operation finishes. The count parameter is populated if the operation completed successfully, otherwise the error parameter is populated.
Returns
An operation which can be canceled.
Since
100

◆ updatedFeaturesWithCompletion:

- (id<AGSCancelable>) updatedFeaturesWithCompletion: (void(^)(AGSFeatureQueryResult *__nullable result, NSError *__nullable error))  completion

Retrieves the features that have been locally updated in the dataset, but not yet in the originating source.

Parameters
completionA block that is invoked when the operation finishes. The result parameter is populated if the operation completed successfully, otherwise the error parameter is populated.
Returns
An operation which can be canceled.
Since
100

◆ validateRelationshipConstraintsForFeature:completion:

- (id<AGSCancelable>) validateRelationshipConstraintsForFeature: (AGSArcGISFeature *)  feature
completion: (void(^)(AGSRelationshipConstraintViolationType relationshipConstraintViolationType, NSError *__nullable error))  completion 

Checks to see if performing edit operations (addFeature:completion: (AGSFeatureTable) or updateFeature:completion: (AGSFeatureTable)) with the provided feature could lead to a relationship constraint violation. This method makes network calls to query for the related features if they are not present locally

Note
Edit operations such as addFeature:completion: (AGSFeatureTable), updateFeature:completion: (AGSFeatureTable) do not error due to relationship constraint violations. Rather, it is the responsibility of the developer to use this method to explicitly check for violations after the edit is performed. Alternatively, you can recover from violations in a back office operation after applying edits or syncing with the service, if you choose to do so. See ArcGIS Desktop Validate Features process.

The following are types of violations that may be reported:

  • AGSRelationshipConstraintViolationTypeOrphaned : In a composite relationship, adding an orphan feature to the destination table without relating it to an origin feature. To recover from this violation, relate the feature to a valid origin feature.
  • AGSRelationshipConstraintViolationTypeCardinality - cardinality violations:
  • In 1:1 relationships, if an origin feature is already related to a destination feature, it is a violation to relate another feature to either of them. To recover from this violation, unrelate the feature from the origin feature.
  • In 1:n relationships, it is a violation to relate a destination feature to more than one origin feature. To recover from this violation, unrelate the feature from the origin feature.
Parameters
featureA feature for which relationship constraints need to be validated.
completionA block that is invoked when the operation finishes. The relationshipConstraintViolationType parameter is populated if the operation completed successfully, otherwise the error parameter is populated.
Returns
An operation which can be canceled.
