getObservations

Gets the collection of DynamicEntityObservation objects associated with this dynamic entity. Use this method to get a collection of DynamicEntityObservation objects associated with this dynamic entity. Observations are associated with a dynamic entity through a shared track ID. For ArcGISStreamService data sources, the track ID field is defined by the ArcGISStreamServiceInfo.trackIdField property.

The returned observations are sorted from the most recent to the oldest.

This method may return an empty collection if the dynamic entity has been purged from the local data cache.
