SimulatedLocationDataSource class final

A location data source that provides simulated device locations for testing.

Use this data source to simulate location updates for a device. It uses a collection of ArcGISLocation that are sequentially passed to LocationDataSource.updateLocation. The location collection can be derived from vertices in a provided polyline, generated evenly along a polyline based on a travel velocity, or assigned to the collection directly.
