AMD: require(["esri/layers/pointCloudFilters/PointCloudValueFilter"], (PointCloudValueFilter) => { /* code goes here */ });
ESM: import PointCloudValueFilter from "@arcgis/core/layers/pointCloudFilters/PointCloudValueFilter.js";
Class: esri/layers/pointCloudFilters/PointCloudValueFilter
Inheritance: PointCloudValueFilterPointCloudFilterAccessor
Since: ArcGIS Maps SDK for JavaScript 4.10

Every lidar point can have a classification that defines the type of surface that reflected the laser pulse. The different categories (for example building, high vegetation, ground) are defined using numeric integer codes in the LAS files. The full list of categories including the corresponding codes can be found in the LAS specification.

PointCloudValueFilter is used to filter points based on the category that they belong to. For example, to display only points that belong to vegetation, the following filter can be set on the layer:

const pcLayer = new PointCloudLayer({
  url: "https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/SONOMA_AREA1_LiDAR_RGB/SceneServer",
  filters: [{
    type: "value",
    field: "CLASS_CODE",
    mode: "include",
    // values includes high vegetation(5)
    values: [5]
  }]
});

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.

// Manually manage handles
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.

fromJSON

Inherited
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. 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.

Parameter
