Property Overview

Property Details

declaredClassStringreadonly inherited

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

definitionExpressionString

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.

Important to note is 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. As a result all features need to be downloaded always for filter evaluation.

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

idNumberreadonly inherited

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

loadErrorErrorreadonly

The Error object returned if an error occurred while loading.

Default Value:null

loadStatusStringreadonly

Represents the status of a load operation.

Value	Description
not-loaded	The object's resources have not loaded.
loading	The object's resources are currently loading.
loaded	The object's resources have loaded without errors.
failed	The object's resources failed to load. See loadError for more details.

Default Value:not-loaded

loadWarningsObject[]readonly

A list of warnings which occurred while loading.

modelNameStringreadonly inherited

The modelName is a standard name for each sublayer. For example the sublayer containing the doors in a building has the modelName "Doors". Use this property to retrieve sublayers in a BuildingSceneLayer.

Example:

// use modelName to identify a sublayer
const doorslayer = buildingSceneLayer.allSublayers.find(function(sublayer) {
  return sublayer.modelName === "Doors";
});

opacityNumber inherited

Opacity of the sublayer.

Default Value:1

popupEnabledBoolean

Indicates whether to display popups when features in the layer are clicked.

Default Value:true

popupTemplatePopupTemplateautocast

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.

rendererRendererautocast

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.

See also:

• Creating visualizations manually

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()
    symbolLayers: [{
      type: "fill",  // autocasts as new FillSymbol3DLayer()
      material: { color: "blue" }
    }]
  }
};

titleString inherited

The title of the sublayer used to identify it in places such as the LayerList and Legend widgets.

typeStringreadonly

The type for this sublayer is always building-component.

visibleBoolean inherited

Indicates if the sublayer is visible in the view.

Default Value:true

Method Overview

Method Details

cancelLoad()

Cancels a load() operation if it is already in progress.

isFulfilled(){Boolean}

isFulfilled() may be used to verify if creating an instance of the class is fulfilled (either resolved or rejected). If it is fulfilled, true will be returned.

Returns:

Type	Description
Boolean	Indicates whether creating an instance of the class has been fulfilled (either resolved or rejected).

isRejected(){Boolean}

isRejected() may be used to verify if creating an instance of the class is rejected. If it is rejected, true will be returned.

Returns:

Type	Description
Boolean	Indicates whether creating an instance of the class has been rejected.

isResolved(){Boolean}

isResolved() may be used to verify if creating an instance of the class is resolved. If it is resolved, true will be returned.

Returns:

Type	Description
Boolean	Indicates whether creating an instance of the class has been resolved.

load(){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.

Returns:

Type	Description
Promise	Resolves when the resources have loaded.

when(callback, errback){Promise}

when() may be leveraged once an instance of the class is created. This method takes two input parameters: a callback function and an errback function. The callback executes when the instance of the class loads. The errback executes if the instance of the class fails to load.

Parameters:

callback Function optional 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.

Example:

// Although this example uses MapView, any class instance that is a promise may use then() in the same way
var view = new MapView();
view.when(function(){
  // This function will execute once the promise is resolved
}, function(error){
  // This function will execute if the promise is rejected due to an error
});
