Parameter:

graphic Graphic optional A Graphic instance.

Returns:

Type	Description

fromJSON(json){*}static

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.

  .then(() => {
    wkidSelect.disabled = false;
});

handle.remove();

// Assign a handle using own()
this.own(reactiveUtils.whenOnce(() => !view.updating)
  .then(() => {
    wkidSelect.disabled = false;
  }));

Parameter:

handleOrHandles WatchHandle|WatchHandle[] Handles marked for removal once the object is destroyed.
