FenceParameters QML Type
|Import Statement:||import Esri.ArcGISRuntime|
- FenceParameters createFromGeoElement(GeoElement geoElement, double bufferDistance)
The FenceParameters defines all of the target geometries of a FenceGeotrigger. Typically, it is made up of many polygons that objects from the GeotriggerFeed can enter or exit. However, if you set a bufferDistance, point and line geometry can also be used. For example, if the condition is "notify me when my position comes within 50 meters of one of my target areas", the fence data would be "my target areas".
Fence data can be created as one of:
Note: You cannot declare or create a component of this type in QML code.
bufferDistance : double
A buffer distance in meters to apply when checking if a FenceGeotrigger condition is met.
Buffers are Geodetic and created using the following default values:
If your fences use point or polyline Geometry then you must set this property to a value greater than
[read-only] fenceParametersType : Enums.FenceParametersType
The type of fence data (read-only).
The type for a specific fence data object.
Emitted when the bufferDistance property changes.
Note: The corresponding handler is
A static method that returns a fence parameters initialized from a geo element and a buffer distance.
- geoElement - A GeoElement to use as a fence area.
- bufferDistance - The buffer distance to apply around fence geometry.
If passed an unsupported GeoElement, this method will return
This method can only be accessed via the Factory object.
