readLabels abstract method

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

Reads label data for a rectangular area defined by two corner tiles.

Default implementations typically combine results from individual tiles, which may be inefficient for large areas.

Precondition: upperLeft.tileX <= lowerRight.tileX && upperLeft.tileY <= lowerRight.tileY

upperLeft Upper-left corner tile of the requested area lowerRight Lower-right corner tile of the requested area Returns combined label data for the area

Implementation

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