Abstract Value Members

  1. abstract def preload(versions: Iterable[Long], tileIds: Iterable[Long]): Unit

    Downloads the data for the requested versions of the given tileIds and puts it into the cache for later retrieval.

    Downloads the data for the requested versions of the given tileIds and puts it into the cache for later retrieval.

    If the data does not fit into the cache completely, this might evict entries from the cache.

  2. abstract def preloadAsync(versions: Iterable[Long], tileIds: Iterable[Long])(implicit ec: ExecutionContext): Future[Unit]

    Downloads the data for the requested versions of the given tileIds and puts it into the cache for later retrieval.

    Downloads the data for the requested versions of the given tileIds and puts it into the cache for later retrieval.
