TileRegionLoadOptions

 
extension TileRegionLoadOptions

  • Initializes a TileRegionLoadOptions, required for TileStore.loadTileRegion(forId:loadOptions:)

    averageBytesPerSecond is not a strict bandwidth limit, but only limits the average download speed. tile regions may be temporarily downloaded with higher speed, then pause downloading until the rolling average has dropped below this value.

    If metadata is not a valid JSON object, then this initializer returns nil.

    Declaration

    Swift

    public convenience init?(geometry: Geometry?,
                         descriptors: [TilesetDescriptor],
                         metadata: Any? = nil,
                         acceptExpired: Bool = false ,
                         networkRestriction: NetworkRestriction = .none,
                         averageBytesPerSecond: Int? = nil)

    Parameters

    geometry

    The tile region’s associated geometry (optional).
    descriptors

    The tile region’s tileset descriptors.
    metadata

    A custom JSON value to be associated with this tile region.
    tileLoadOptions

    Restrict the tile region load request to the specified network types. If none of the specified network types is available, the load request fails with an error.
    averageBytesPerSecond

    Limits the download speed of the tile region.

  • Limits the download speed of the tile region.

    Note that this is not a strict bandwidth limit, but only limits the average download speed. tile regions may be temporarily downloaded with higher speed, then pause downloading until the rolling average has dropped below this value.

    If unspecified, the download speed will not be restricted.

    Declaration

    Swift

    public var averageBytesPerSecond: Int? { get }

  • The geometry supported by these options.

    Declaration

    Swift

    public var geometry: Geometry? { get }
