ESM: import BuildingComponentSublayer from "@arcgis/core/layers/buildingSublayers/BuildingComponentSublayer.js";
Class: esri/layers/buildingSublayers/BuildingComponentSublayer
Inheritance: BuildingComponentSublayer BuildingSublayer Accessor
Since: ArcGIS Maps SDK for JavaScript 4.10

BuildingComponentSublayers contain 3D Object features representing building components like doors, pipes or AC units. They are sublayers in a BuildingSceneLayer either directly or as part of a BuildingGroupSublayer. This sublayer is similar to a 3D Object SceneLayer, it can be visualized with a specific renderer, popups can be customized using popupTemplate and SQL filters can be applied by setting a definitionExpression.

Starting with version 4.17, BuildingComponentSublayers support attribute or spatial queries if the the BuildingSceneLayer has an associated feature layer.

Property Details

declaredClass

Inherited
Property
declaredClass Stringreadonly
Inherited from Accessor

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

definitionExpression

Property
definitionExpression String

The SQL where clause used to filter features on the client. Only the features that satisfy the definition expression are displayed in the View. Setting a definition expression is useful when only a subset of the data in the layer should be displayed.

Setting the definition expression of a layer automatically updates all layer views.

If the definition expression is set after the layer has been added to the map, the view will automatically refresh itself to display the features that satisfy the new definition expression.

Note that the initial loading time of the features remains unchanged, even if they are filtered. This happens because, as opposed to Feature Layers, feature filtering is done client-side. This means that all features need to be downloaded for filter evaluation.

This property is evaluated on the client using the cached attributes and it only supports standardized SQL.

id

Inherited
Property
id Numberreadonly
Inherited from BuildingSublayer

The sublayer's layer id as defined by the Scene Service.

isEmpty

Inherited
Property

To include fields in all sublayers, use the outFields property of the parent layer.

Default Value:null

popupEnabled

Property
popupEnabled Boolean

Indicates whether to display popups when features in the layer are clicked. The layer needs to have a popupTemplate to define what information should be displayed in the popup. Alternatively, a default popup template may be automatically used if Popup.defaultPopupTemplateEnabled is set to true.

Default Value:true
See also

popupTemplate

Property
popupTemplate PopupTemplateautocast

The popup template for the sublayer. When set, the popupTemplate allows users to access attributes and display their values in the view's popup when a feature is selected using text and/or charts. See the PopupTemplate sample for an example of how PopupTemplate interacts with a FeatureLayer. Setting a PopupTemplate on this layer type is done in the same way as a FeatureLayer.

A default popup template is automatically used if no popupTemplate has been defined when Popup.defaultPopupTemplateEnabled is set to true.

renderer

Property
renderer Rendererautocast

The renderer assigned to the sublayer. The renderer defines how to visualize each feature in the sublayer. Depending on the renderer type, features may be visualized with the same symbol, or with varying symbols based on the values of provided attribute fields or functions.

Example
// all features in the layer will be visualized with
// a blue color
sublayer.renderer = {
  type: "simple",  // autocasts as new SimpleRenderer()
  symbol: {
    type: "mesh-3d",  // autocasts as new MeshSymbol3D()

load

Method
load(signal){Promise}

Loads the resources referenced by this class. This method automatically executes for a View and all of the resources it references in Map if the view is constructed with a map instance.

This method must be called by the developer when accessing a resource that will not be loaded in a View.

The load() method only triggers the loading of the resource the first time it is called. The subsequent calls return the same promise.

It's possible to provide a signal to stop being interested into a Loadable instance load status. When the signal is aborted, the instance does not stop its loading process, only cancelLoad can abort it.

Parameter
signal AbortSignal
optional

Signal object that can be used to abort the asynchronous task. The returned promise will be rejected with an Error named AbortError when an abort is signaled. See also AbortController for more information on how to construct a controller that can be used to deliver abort signals.

Returns
Type Description
Promise Resolves when the resources have loaded.

queryExtent

Since: ArcGIS Maps SDK for JavaScript 4.17 BuildingComponentSublayer since 4.10, queryExtent added at 4.17.

Executes a Query against the associated feature service and returns the 2D Extent of features that satisfy the query. At the moment the 3D Extent can be returned by using BuildingComponentSublayerView.queryExtent(), but this will return the 3D extent only for features currently in the view. The query succeeds only if the BuildingSceneLayer has an associated feature layer. If an associated feature layer is not available, then an error with the name buildingscenelayer:query-not-available is thrown. Read more about queries in the Querying section of the BuildingSceneLayer class description.

The function to call when the promise resolves.

errback Function
optional

The function to execute when the promise fails.

Returns
Type Description
Promise Returns a new promise for the result of callback that may be used to chain additional functions.
