readLabels abstract method

Future<DatastoreReadResult?> readLabels(
  1. Tile upperLeft,
  2. Tile lowerRight
)

Reads data for an area defined by the tile in the upper left and the tile in the lower right corner. The default implementation combines the results from all tiles, a possibly inefficient solution. Precondition: upperLeft.tileX <= lowerRight.tileX && upperLeft.tileY <= lowerRight.tileY

@param upperLeft tile that defines the upper left corner of the requested area. @param lowerRight tile that defines the lower right corner of the requested area. @return map data for the tile.

Implementation

Future<DatastoreReadResult?> readLabels(Tile upperLeft, Tile lowerRight);
