Inheritance: BuildingFilter→Accessor

Since: ArcGIS Maps SDK for JavaScript 4.12

The BuildingFilter class defines a set of conditions that can be used to show or hide specific features of a BuildingSceneLayer in the SceneView. For example, if you want to see parts of a building that are on the second floor, you can set a filter to only show the second floor. The filter can be activated on a layer by adding it to the BuildingSceneLayer.filters collection and assigning id to BuildingSceneLayer.activeFilterId. Once the filter is activated, only the features that satisfy the conditions defined by filterBlocks are displayed in the SceneView.

Example

// define a floor filter
const buildingFilter = new BuildingFilter({
  filterBlocks: [{
    // an SQL expression that filters using the BldgLevel field
    filterExpression: "BldgLevel = 3",
    filterMode: {
      type: "wire-frame",
      edges: {
         type: "solid",
         color: [0, 0, 0, 0.8]
      }
    }
  }]
});
// set the filter in the filters array on the layer
buildingLayer.filters = [buildingFilter];
// specify which filter is the one that should be applied
buildingLayer.activeFilterId = buildingFilter.id;

declaredClass

readonlyinherited Property

Type: string

Inherited from: Accessor

The name of the class. The declared class name is formatted as esri.folder.className.

description

Property

Type: string | null | undefined

Description of the filter for display in UIs, for example when the filter is edited in ArcGIS Pro.

filterBlocks

autocast Property

Type: Collection<BuildingFilterBlock> | null | undefined

Filter blocks define which features should be visible in the affected BuildingSceneLayer and how the filtered features are drawn. A filter should contain at least one filter block.

The order of filter blocks influences the order in which the filter blocks are applied. For example, if a filter block using a wire-frame mode precedes a solid filter block in the collection, elements that match either filter block will be drawn as wireframe.

id

readonly Property

Type: string

Unique filter id. Assign this id to BuildingSceneLayer.activeFilterId to activate the filter.

name

Property

Type: string | null | undefined

Name of the filter for display in UIs, for example when the filter is edited in ArcGIS Pro.

fromJSON

inheritedstatic Method

Signature: fromJSON (json: any): any

Inherited from: JSONSupportMixin

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.

Parameters

Parameter	Type	Description	Required
json	any	A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns: any
Returns a new instance of this class.

toJSON

inherited Method

Signature: toJSON (): any

Inherited from: JSONSupportMixin

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.

Returns: any
The ArcGIS portal JSON representation of an instance of this class.
