Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor 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.

const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();

Parameters

handleOrHandles WatchHandle|WatchHandle []

Handles marked for removal once the object is destroyed.

groupKey *

optional

Key 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.

fromGraphic Method fromGraphic(graphic){PointBarrier}static Since: ArcGIS Maps SDK for JavaScript 4.24 PointBarrier since 4.23, fromGraphic added at 4.24.

Creates a PointBarrier from the parsed Graphic. The method assumes that the graphic's attributes conform to the route layer item schema.

Parameter

graphic Graphic

optional

A Graphic instance.

Returns

Type	Description
PointBarrier	A PointBarrier instance.

fromJSON Method fromJSON(json){*}static

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product.
