sourceSettings property

Defines the collection of snapping sources and whether or not each is enabled for snapping.

Call SnapSettings.syncSourceSettings to populate this collection with a SnapSourceSettings for each valid SnapSource present in the connected ArcGISMapViewController. SnapSettings is connected to an ArcGISMapViewController via GeometryEditor.snapSettings, and ArcGISMapViewController.geometryEditor. If there is no connected ArcGISMapViewController, or the map view and the associated map contains no valid SnapSource objects, then the collection will be empty after SnapSettings.syncSourceSettings returns.

The order of SnapSourceSettings objects will match the order that the associated SnapSource objects appear in the GeoModel.operationalLayers and GeoViewController.graphicsOverlays collections, with objects from GeoModel.operationalLayers appearing first, followed by GeoViewController.graphicsOverlays objects, in order. The collection will not contain a SnapSourceSettings for any SnapSource which is not yet LoadStatus.loaded when SnapSettings.syncSourceSettings is called.

As snapping is used to maintain data integrity between different sources of data, only SnapSource objects that provide full resolution geometries as considered valid for creating a SnapSourceSettings object - see SnapSource for more information.
