Default is xyFootprint if geometryType is esriGeometryMultiPatch.

Supports feature services whose data source is a multipatch featureclass. The maximum number of observations being shown for each unique track. The maximum allowable offset, only applicable for layers that are not editable. When the layer is loaded, the value becomes 'true', and layer properties can be accessed. Unique ID of the layer that the FeatureLayer was constructed against. Label definition for this layer, specified as an array of label classes. The html popup type defined for the layer. Indicates whether the layer displays all features intersecting the current view. Geometry type of the features in the layer. The name of the layer's primary display field.Īpplicable to ArcGIS Online hosted feature services. The description of the layer as defined in the map service. Indicates the default visibility for the layer. Metadata describing the default definition expression for the layer as defined by the service. List of attribute fields added as custom data attributes to graphics node.

However, they are not supported by all versions of all browsers. Most browsers are supporting WebSockets in recent versions.

Use the purgeOptions construction option to define rules that specify how to remove data when new messages are received and the layer is refreshed.

The number of features coming from a real-time feed can overload the browser and make the browser unresponsive. You may also use your own web socket server, as long as it emits geographic features in the Esri JSON format. To learn more about this, please see the Stream Services documentation. In addition, version 10.3 of ArcGIS GeoEvent Extension for Server exposes stream services. The ArcGIS GeoEvent Processor for Server is a tool you may use to set up and configure your data stream. When a stream layer is added to a map, users are able to see any real-time updates pushed out by the server.Ī real-time-enabled data server is required in order to use this class. While the feature layer is used to map relatively static data, the stream layer is suitable when you would like to map dynamic streams of data that are unbounded and continuous. It connects to a server that emits geographic features continuously. (Added at v3.6)The stream layer extends the feature layer to add the ability to connect to a stream of data using HTML5 WebSockets.
