Export
A task used to export vector tiles and optionally a portal item's vector tile style resources. Vector tiles are exported as a vector tile package (.vtpk) file, see VectorTileCache.
A portal item can contain a custom style resources overriding the vector tile services default style and this can be checked with ExportVectorTilesTask.hasStyleResources. The custom style is exported separately as an ItemResourceCache.
The export vector tiles task can be initialized with a URL using ExportVectorTilesTask.ExportVectorTilesTask(String). The URL can be to:
A vector tile server that ends in "VectorTileServer" and is the rest end-point used to export vector tile packages. The vector tile service must be enabled for export or the task will fail to load.
A portal item for a vector tile service or a vector tiled layer with a custom style applied.
A vector basemap layer created using a BasemapStyle.
Alternatively a PortalItem, referencing a vector tile service or a custom style for a vector tiled layer, can be used with ExportVectorTilesTask.ExportVectorTilesTask(PortalItem).
When using Esri provided vector basemaps that do not support exporting tiles (such as the ArcGIS streets basemap - see BasemapStyle.ArcGISStreets), an alternative service that supports exporting tiles will be used instead.

Constructors
Initialize an export vector tiles task with a portal item of type PortalItemType.VectorTileService. If the portal item is not of type PortalItemType.VectorTileService the task will fail to load.
Initialize an export vector tiles task with a URL to a vector tile service. The URL can be for:
Properties
Indicates if the task's portal item has any associated style resources that override the default style of the vector tile service. This property will be set to true if the export vector tile task has been loaded and the task's portal item has style resources. The portal item's style resources override the default style of the vector tile service and can be exported as ItemResourceCache.
The task's portal item which must be of type PortalItemType.VectorTileService. This property can only be set when the task is load status LoadStatus.NotLoaded or LoadStatus.FailedToLoad If the portal item is not of type PortalItemType.VectorTileService the task will fail to load. A vector tile service can be referenced by an item in a portal of type PortalItemType.VectorTileService. This item can also contain custom style resources see ExportVectorTilesTask.hasStyleResources which can be exported as ItemResourceCache.
The task's VectorTileSourceInfo representing the source metadata for a vector tile service.
Inherited properties
The API key allows your app to access ArcGIS location services and private portal items. An API key is a unique long-lived access token that is used to authenticate and monitor requests to ArcGIS location services and private portal items. You can create and manage an API key using your portal when you sign in with an ArcGIS Location Platform account or an ArcGIS Online account with administrator access or a custom role that has the Generate API keys privilege. To learn how to create and manage API keys, go to the Create an API Key tutorial. You must ensure that your API key has the correct privileges to access secure resources.
The load status.
Functions
Creates and returns the default parameters for the export vector tile task. This function is asynchronous because it makes use of the service metadata to populate the ExportVectorTilesParameters object. Calling this function will trigger the ExportVectorTilesTask to be loaded, unless it is already loaded.
Return a new export vector tiles job that will download a custom style from a portal item as an item resource cache. The job will return the item resource cache without a vector tile cache. This is useful when a number of different styles are applied to the same underlying vector tile service. This avoids exporting multiple copies of the same tiles.
Returns a new export vector tiles job that can be used to generate and download a vector tile package containing the vector tiles specified by the parameters (ExportVectorTilesParameters).
Return a new export vector tiles job that can be used to generate and download a vector tile package and return a custom style as an item resource cache.
