      • getAreaOfInterest

        public Geometry getAreaOfInterest()
        Gets the geometry that represents the area of vector tiles to be exported.

        The supported geometry types for the area of interest are Envelope and Polygon. The area of interest must have a spatial reference.

        Where a Polygon is supplied, features and tiles will be filtered according to the polygon geometry, which can help reduce the size of the resulting offline map. Note that the filtered set of tiles may vary, depending on the underlying service.

        Returns:
        the Geometry that represents the area of tiles to be exported. If null the full extent of the service will be exported.

        100.2.0
      • setAreaOfInterest

        public void setAreaOfInterest​(Geometry areaOfInterest)
        Sets the geometry that represents the area of vector tiles to be exported.

        The supported geometry types for the area of interest are Envelope and Polygon. The area of interest must have a spatial reference.

        Where a Polygon is supplied, features and tiles will be filtered according to the polygon geometry, which can help reduce the size of the resulting offline map. Note that the filtered set of tiles may vary, depending on the underlying service.

        Parameters:
        areaOfInterest - the Geometry that represents the area of vector tiles to be exported, can be null in which case the full extent of the service will be exported.
        Throws:
        IllegalArgumentException - if the geometry is anything other than null or an Envelope or a Polygon

      • setEsriVectorTilesDownloadOption

        public void setEsriVectorTilesDownloadOption​(EsriVectorTilesDownloadOption esriVectorTilesDownloadOption)
        Sets how Esri vector tiled basemap layers will be downloaded.

        This property lets you choose how to download Esri vector tiled basemap layers. It only applies when taking an Esri vector tile basemap service offline.

        When taking an Esri vector tiled basemap service offline (for example to create a VectorTileCache on your device), you can choose from different versions of the service depending on your use case.

        Primary considerations are the download speed and the size of the resulting .vtpk file. Among other things, file size is influenced by the number of fonts downloaded from the service. Esri vector tiled basemap layers use fonts as part of their style resources - see the vector-tile-style documentation. When you take a vector tiled layer offline, these fonts are downloaded as part of the VectorTileCache.

        Esri services also offer an alternative version with a reduced font package size. This omits the large Arial Unicode font, which greatly reduces the download size. You can view the set of reduced font vector tile services here.

        • If you choose EsriVectorTilesDownloadOption.USE_ORIGINAL_SERVICE, the full set of resources used by the original online service, including all fonts, will be downloaded. This increases the download size of the VectorTileCache but ensures that the offline layer will display the same as the original online data.
        • If you choose EsriVectorTilesDownloadOption.USE_REDUCED_FONTS_SERVICE, the smaller set of fonts used by the alternative, for export, version of the service will be downloaded. This reduces the download size of the VectorTileCache but is not suitable for all locales or when your offline vector tiled layer includes certain language characters. For example, this option will not display Chinese, Japanese, Thai, Korean or Georgian characters. If an alternative, for export, version of the service cannot be found, the original service will be used.
        The default value is EsriVectorTilesDownloadOption.USE_ORIGINAL_SERVICE.
        Parameters:
        esriVectorTilesDownloadOption - describes how Esri vector tiled basemap layers will be downloaded
        Throws:
        IllegalArgumentException - if esriVectorTilesDownloadOption is null

      • setMaxLevel

        public void setMaxLevel​(int maxLevel)
        Sets the maximum level of details to export vector tiles.

        This number represents the maximum level of detail to export. The vector tile export will always take levels 0 and all in between levels up to and including the value of max level. The larger the level the more tiles will be included. The default value is -1, which must be set to a valid value >= 0.

        Parameters:
        maxLevel - the maximum level of details to export
        Throws:
        IllegalArgumentException - if maxLevel is negative

        public int getMaxLevel()
        Gets the maximum level of details to export.
        Returns:
        the maximum level of details to export
