FeatureLayerDataSource

Interface

FeatureLayerDataSource is created from a single feature layer of feature service, map service or webmap/webscene.

The source of feature layer data source may be from -

an array directly ( sourceRecords ), isDataInDataSourceInstance is true for such data sources, or,
an ArcGIS Maps SDK for JavaScript feature layer, or,
an AGOL/portal item or a remote database.

Please note, for the 2, the feature layer can be both client-side or server-side.

Interface Property

updateSelectionInfo: (options: SelectOptions, triggerDataSource: DataSource, forceCheck?: boolean) => void

Update selected records in data source info if the current data source listens selection change (see setListenSelection ) or the current data source is the trigger data source (that is to say, select via it).

Before update info, will check whether these selected records match filters of the current data source firstly, and then only set the matched selected records to info. Will skip the check in some cases to improve performance if the forceCheck is not passed in or is false. For example, if the curren data source is main data source (we suppose that main data source contains all records, no need to check). But if the forceCheck is true, won't skip the check.
