isSyncEnabled property
True if the geodatabase was originally downloaded from a sync-enabled ArcGIS feature service, false otherwise.
A sync-enabled geodatabase can be requested from an ArcGIS feature service using the GenerateGeodatabaseJob or the GenerateOfflineMapJob. It can also be downloaded as part of a PreplannedMapArea. See GeodatabaseSyncTask and OfflineMapTask for more information.
If true, the geodatabase's data can be synchronized with its original ArcGIS feature service.
