esri/widgets/LineOfSight/LineOfSightTarget
This class represents a target point for a LineOfSight analysis. The location represents the Point the observer is looking at, while visible indicates whether the line between the observer and the target intersects 3D graphics, integrated mesh or the ground. If it intersects 3D graphics, then the intersectedGraphic property will point to the first intersected graphic. The intersectedLocation corresponds to the first intersection with a 3D graphic, integrated mesh or the ground.

Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25Accessor since 4.0, addHandles added at 4.25. -
Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.
// Manually manage handles const handle = reactiveUtils.when( () => !view.updating, () => { wkidSelect.disabled = false; }, { once: true } ); this.addHandles(handle); // Destroy the object this.destroy();ParametershandleOrHandles WatchHandle|WatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.
