isRoutingDataAvailable

public boolean isRoutingDataAvailable(MapDescriptor mapDescriptor)

Description copied from interface: RoutingService

Whether routing data for the given map is present locally. Derived by default from the RoutingService.getCoverageTiles(BoundingBox) grid of the map's bounding box -- an empty grid counts as not available. Distinct from calculateRemainingDownloadSize() == 0, which is also true when nothing is published for the region and therefore nothing is missing.

calculateRemainingDownloadSize

public long calculateRemainingDownloadSize(List<MapDescriptor> mapDescriptors)

downloadRoutingData

public void downloadRoutingData(List<MapDescriptor> mapDescriptors)

getCoverageTiles

public Map<BoundingBox,Boolean> getCoverageTiles(BoundingBox area)

getRoutingCoverage

public Polygon getRoutingCoverage(MapDescriptor mapDescriptor,
 Runnable onAvailable)

Description copied from interface: RoutingService

The exact area for which the routing data of the given map is valid, if known. Never blocks: returns null if the area is not (yet) known, in which case the caller falls back to the map's bounding box. If the area is fetched in the background, onAvailable is called once it arrives.
