Manages the data displayed by a floor-aware map or scene, allowing filtering based on floor levels. A FloorManager must be loaded before you can access its site, facility, and level properties. When a map's floor manager is loaded, floor-aware layers display only data associated with the ground floor by default. When a scene's floor manager is loaded, floor-aware layers display data from all floors by default. You can filter the data displayed by floor-aware layers by toggling the FloorLevel.isVisible property of levels in the floor manager. The FloorManager will fail to load if:
The map/scene associated with the floor manager is not floor-aware.
The mandatory facility or level layer doesn't exist.
It is unable to get the facilities or levels from their respective layers.
It is unable to get the sites from a specified site layer.
