TileStore

open class TileStore

TileStore manages downloads and storage for requests to tile-related API endpoints, enforcing a disk usage quota: tiles available on disk may be deleted to make room for a new download. This interface can be used by an app developer to set the disk quota. The rest of TileStore API is intended for native SDK consumption only.
