BuildingComponentSublayerView | API Reference | ArcGIS Maps SDK for JavaScript 4.30

Represents the sublayer view of a BuildingComponentSublayer. The sublayer view can be used for queries of features that are loaded in the view. Sublayer views can be accessed via the sublayerViews property on BuildingSceneLayerView:

// query all sublayers for features that satisfy the sql expression
let query = new Query();
query.where = "FamilyType = 'Landscape'";
view.whenLayerView(buildingSceneLayer).then(function(bslv) {
   bslv.sublayerViews.forEach(function(componentSublayerView) {
     componentSublayerView.queryFeatures(query).then(function(result) {
       console.log(result.features);
     });
   });
});

Queries on the BuildingComponentSublayerView is executed against features that have been loaded for the current view. This means that only visible features are guaranteed to be available once the layer has finished updating. The query methods on the BuildingComponentSublayerView should not be used when the intention is to query or search within the whole dataset, instead the query methods on the BuildingComponentSublayer should be used.

The highlight method can be called on a specific sublayer view:

view.whenLayerView(buildingSceneLayer).then(function(bslv) {
  // get the sublayer view of the component sublayer with id 1
  const sublayerView = bslv.sublayerViews.find(function(sublayerView) {
    return sublayerView.sublayer.id === 1;
  });
  const query = sublayerView.createQuery();
  query.spatialRelationship = "contains";
  query.geometry = polygonGeometry;
  // query sublayer view
  sublayerView.queryObjectIds(query).then(function(result) {
    sublayerView.highlight(result);
  });
});

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.

// 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.

createQuery Method createQuery(){Query}

Creates a query parameter object that can be used to fetch features as they are being displayed. It sets the query parameter's outFields property to ["*"] and returnGeometry to true. The output spatial reference is set to the spatial reference of the view. The esri/layers/buildingSublayers/BuildingComponentSublayer.html#definitionExpression that currently applies to the sublayer view is also incorporated in the returned query object.

Returns

Type	Description
Query	The query object

hasHandles Inherited Method hasHandles(groupKey){Boolean} Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, hasHandles added at 4.25.

Returns true if a named group of handles exist.

Parameter

groupKey *

optional

A group key.

Returns

Type	Description
Boolean	Returns `true` if a named group of handles exist.

Example

// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

highlight Method highlight(target){Handle}

Highlights the given feature(s).

Parameter

target Graphic|Graphic []|Number|Number []

optional

The feature(s) to highlight. When passing a graphic or array of graphics, each feature must have a valid objectID. You may alternatively pass one or more objectIDs as a single number or an array.

Returns

Type	Description
Handle	Returns a highlight handler with a `remove()` method that can be called to remove the highlight.

queryExtent Method queryExtent(query, options){Promise<object>}

Executes a Query against features in the layer view and returns the 3D Extent of features that satisfy the query. If query parameters are not provided, the extent and count of all loaded features are returned.

Read more about queries in the Query section of the BuildingSceneLayer class description.

To query for the extent of features directly from a Scene Service rather than those loaded for the current view, you must use the BuildingComponentSublayer.queryExtent() method.

For making attribute based queries on a BuildingComponentSublayerView you need to specify the required fields in the outFields property of the BuildingComponentSublayer to ensure that attribute values are available on the client for querying. You can use availableFields to inspect which fields are available on the client.

Known Limitations

Spatial queries have the same limitations as those listed in the projection engine documentation.
Spatial queries on BuildingComponentSublayerView use the Extent of the feature and not the footprint when calculating the spatial relationship with the query geometry. This means that a feature might be returned from the query, even though its footprint is not in a spatial relationship with the geometry.
Currently only intersects, contains, and disjoint spatialRelationships are supported on spatial queries.
Spatial queries are not currently supported if the BuildingComponentSublayerView has any of the following SpatialReferences:
- GDM 2000 (4742) - Malaysia
- Gsterberg (Ferro) (8042) - Austria/Czech Republic
- ISN2016 (8086) - Iceland
- SVY21 (4757) - Singapore

Parameters

query Query autocast

optional

Autocasts from Object

Specifies the attributes and spatial filter of the query. When no parameters are passed to this method, all features in the client are returned.

options Object

optional

An object with the following properties.

Specification

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

queryFeatureCount Method queryFeatureCount(query, options){Promise<number>}

Executes a Query against features in the layer view and returns the number of features that satisfy the query. If query parameters are not provided, the count of all loaded features is returned.

To query for the count of features directly from a Scene Service rather than those loaded for the current view, you must use the BuildingComponentSublayer.queryFeatureCount() method.
