@arcgis/core/layers/support/LevelLayerInfo
The LevelLayerInfo class describes the footprint of each occupiable floor contained in a managed facility. The FloorFilter widget uses this class to identify what floor levels exist in the layer to use for filtering.

Property Details
-
The field name from the layer that defines the unique ID of a feature's associated facility. This is used to identify the feature's associated facility feature in floor-aware maps. A feature can only be related to a single facility using this field.
-
The id for an operational layer in the map. This allows LevelLayerInfo to refer to an operational layer that contains level features. When configuring a floor-aware map manually, as opposed to configuring it in ArcGIS Pro, this value needs to be set with the ID value from the appropriate Layer object, whether a FeatureLayer or SceneLayer.
-
The field name from the layer that defines a unique ID for the feature.
-
The field name from the layer that defines the level floor number in a particular facility.
-
The field name from the layer that defines the level name of a feature. The level name is used to support floor filtering in floor-aware apps.
-
The field name from the layer that defines the level short name of a feature. The level short name supports floor filtering in floor-aware apps. Some floor-aware apps only display a short name in the floor filter, others may use the longNameField or allow toggling between the two.
-
This value references the numeric ID of the sublayer if the Level layer is a map service sublayer instead of a feature layer.
-
The field name from the layer that defines the order of display and reference to floors in the Indoor Positioning System. It uses a zero-based ordering system to define the floor order. The ground level of each facility is represented as zero. Positive values represent floors above ground, and negative values represent floors below ground. Values must be continuous and a value in the sequence cannot be skipped.

Method Details
-
Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25Accessor 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();ParametershandleOrHandles WatchHandle|WatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey 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.
-
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
jsonparameter 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.Parameterjson ObjectA 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.
