RealtimeFeatureClass Class
In This Topic
Represents a real-time table with a spatial column.
Object Model
Syntax
Public NotInheritable Class RealtimeFeatureClass Inherits ArcGIS.Core.Data.FeatureClass Implements System.IDisposable
public sealed class RealtimeFeatureClass : ArcGIS.Core.Data.FeatureClass, 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";
// Note: call within 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 (RealtimeFeatureClass 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
{
// Note: call within QueuedTask.Run()
{
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
{
// Note: call within QueuedTask.Run()
{
using (var rfc = streamLayer.GetFeatureClass())
using (var rfc_def = rfc.GetDefinition())
{
if (rfc_def.HasTrackIDField())
{
var fld_name = rfc_def.GetTrackIDField();
}
}
}
}
