RealtimeFeatureClass Class

In This Topic

Represents a real-time table with a spatial column.

Object Model

Syntax

C#
Visual Basic (Declaration)

public sealed class RealtimeFeatureClass : ArcGIS.Core.Data.FeatureClass, System.IDisposable

Public NotInheritable Class RealtimeFeatureClass 
   Inherits ArcGIS.Core.Data.FeatureClass
   Implements System.IDisposable

Remarks

Streaming does not start automatically. Call StartStreaming explicitly to start receiving feature stream.

Example

Connect to a real-time feature class from a real-time datastore

var url = "https://geoeventsample1.esri.com:6443/arcgis/rest/services/AirportTraffics/StreamServer";
     
await QueuedTask.Run(() =>
{
  var realtimeServiceConProp = new RealtimeServiceConnectionProperties(
                                   new Uri(url),
                                   RealtimeDatastoreType.StreamService
                                );
  using (var realtimeDatastore = new RealtimeDatastore(realtimeServiceConProp))
  {
    //A Realtime data store only contains **one** Realtime feature class (or table)
    var name = realtimeDatastore.GetTableNames().First();
    using (var realtimeFeatureClass = realtimeDatastore.OpenTable(name) as RealtimeFeatureClass)
    {
      //feature class, by default, is not streaming (opposite of the stream layer)
      realtimeFeatureClass.StartStreaming();
      //TODO use the feature class
      //...
    }
  }

});

Check the Realtime Feature Class is Track Aware

using (var rfc = streamLayer.GetFeatureClass())
using (var rfc_def = rfc.GetDefinition())
{
  if (rfc_def.HasTrackIDField())
  {
    //Track aware
  }
}

Get the Track Id Field from the Realtime Feature class

//Must be on QueuedTask
using (var rfc = streamLayer.GetFeatureClass())
using (var rfc_def = rfc.GetDefinition())
{
  if (rfc_def.HasTrackIDField())
  {
    var fld_name = rfc_def.GetTrackIDField();

  }
}
