A condition which monitors the dynamic elements of the geotrigger feed for enter/exit against the fences defined by the Fence Parameters.

let fenceGeotrigger = new FenceGeotrigger({ name: "Example Geotrigger - Notify when I am within 50m of my target areas.", enterExitRule: "enter-intersects-and-exit-does-not-intersect", feed: { filterExpression: { title: "Location filter", expression: "return $locationupdate.horizontalaccuracy <= 20" } }, fenceNotificationRule: "enter", feedAccuracyMode: "use-geometry-with-accuracy", fenceParameters: { bufferDistance: 50, fenceSource: { layerUrl: "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Recreation/MapServer/0" }, }, notificationOptions: { expressionInfo: { "title": "Expression", "expression": "'You have entered' + $fencefeature.AREA_NAME" } }})Constructors

enterExitRule
- Type
- EnterExitRule
The rule that determines whether a fence polygon has been entered or exited by the geometry from a feed. The feedAccuracyMode must be set to use-geometry-with-accuracy for this property to have an effect.
| Enter exit rule | Description |
|---|---|
| enter-intersects-and-exit-does-not-intersect | A fence polygon is entered when it intersects a feed geometry and exited when it no longer intersects. |
| enter-contains-and-exit-does-not-contain | A fence polygon is entered when it contains a feed geometry and exited when it is no longer contained. |
| enter-contains-and-exit-does-not-intersect | A fence polygon is entered when it contains a feed geometry and exited when it no longer intersects. |
- Default value
- "enter-contains-and-exit-does-not-intersect"
feedAccuracyMode
- Type
- FeedAccuracyMode
Indicates how the geotrigger will use accuracy information from a feed.
| Feed accuracy mode | Description |
|---|---|
| use-geometry | The reported geometry from a feed will be used. |
| use-geometry-with-accuracy | The feed geometry will be used in conjunction with accuracy information. |
- Default value
- "use-geometry"
fenceNotificationRule
- Type
- FenceNotificationRule | null | undefined
Indicates the type of event that will trigger notifications for the Fence Geotrigger. For example, a value of enter will result in notifications when the geometry of the feed enters a fence polygon.
fenceParameters
- Type
- FeatureFenceParameters | null | undefined
An object defining the fences to use for this Geotrigger.
notificationOptions
- Type
- GeotriggerNotificationOptions | null | undefined
Options that control the notification information sent to a client app when a Geotrigger condition is met.
Methods
fromJSON
- Signature
-
fromJSON (json: any): any
Creates a new instance of this class and initializes it with values from a JSON object
generated from an ArcGIS product. The object passed into the input json
parameter often comes from a response to a query operation in the REST API or a
toJSON()
method from another ArcGIS product. See the Using fromJSON()
topic in the Guide for details and examples of when and how to use this function.
Parameters
| Parameter | Type | Description | Required |
|---|---|---|---|
| json | A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects. | |
- Returns
- any
Returns a new instance of this class.
clone
- Signature
-
clone (): this
Creates a deep clone of this object. Any properties that store values by reference will be assigned copies of the referenced values on the cloned instance.
- Returns
- this
A deep clone of the class instance that invoked this method.
toJSON
- Signature
-
toJSON (): any
Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.
- Returns
- any
The ArcGIS portal JSON representation of an instance of this class.
