Arc
Displays data from an ArcGIS vector tiled data source. The ArcGIS Vector Tiled Layer is similar to the ArcGIS Tiled Layer. An ArcGIS Vector Tiled Layer is loaded from ArcGIS online, ArcGIS Enterprise, ArcGIS Server, or a local vector tile layer package file. The tile data format is optimized to reduce network bandwidth and reduce CPU load while rendering the tiles. Vector Tiled Layers are appropriate for basemap, reference and possibly operational layers. They do not contain any feature data, and do not support identify or search operations.
Vector tiles are an alternative to raster tile basemap layers. Instead of pixels (raster), the cartography is delivered using 2D points. The points describe lines, polygons, or the locations of labels and marker symbols. The file format of tiles is binary and conforms to the Mapbox Vector Tile Specification. This specification allows a more continuous visual experience between levels of detail compared to raster tiles. The vector tile file format also requires less space than raster tiles.
You can create a vector tiled layer using either a URI or a portal item. The URI can point to a vector tile source, a vector tile style sheet, or a local vector tile package file. The portal item will contain a URI to a vector tile stylesheet. The style sheet describes the appearance of the geometry and must be in the Mapbox GL Style format. The style sheet also contains a URI to a vector tile source. The source must be in the Mapbox TileJSON format. The source info includes a URI to a default style sheet.
More than one vector tile style sheet can use the same source. Both the source info and the style sheet are human readable JSON files.
Vector tile packages can also be downloaded from a ArcGIS Online vector tile service. The vector tile package is a single file (.vptk) that contains all of the tile data files, the source information, a style sheet, and the font and symbol marker resources required to display the map.
Vector tile packages are also distributed inside Mobile Map Packages. The MMPK contains JSON that points to the location of the vector tile style sheet or the root of the vector tile package data.

Constructors
Creates an ArcGIS Vector Tiled Layer object from an item.
Creates an ArcGIS Vector Tiled Layer object. Use this object to create an ArcGIS vector tiled layer.
Creates an ArcGIS Vector Tiled Layer object from a vector tile cache and an item resource cache containing a custom style for this vector tile layer.
Functions
Cancels loading metadata for the Loadable object.
Clones the ArcGISVectorTiledLayer.
Fetches the list of legend info.
Returns the layer content's effective visibility at the specified scale. Returns the effective layer content visibility. This effective visibility takes care of the effective visibility of the parents at the specified scale. Will return false if an error occurs.
Properties
An API key is a unique key used to authorize access to specific services and resources in ArcGIS Online. It is also used to monitor access to those services.
The unique identifying string for the layer, for example specified in a map or scene. The id is used by other parts of this API to refer to a specific Layer, such as in a set of FeatureFenceParameters or a FacilityLayerDefinition. If not supplied, all layers will be assigned a unique id when created.
