partitionIds: Iterator[TileId]
Gets the tile IDs available from this loader.
Gets the tile IDs available from this loader.
This will only return tile IDs for which the com.here.platform.location.dataloader.core.TileLoader#get method will return a non-empty value.
Whereas the com.here.platform.location.inmemory.geospatial.TileResolver can be used to determine all of the tile IDs that cover a certain area of the earth (or even the whole earth), it does not know which tiles actually have data. This method allows you to discover tiles that actually contain data.
E.g. a data loader for a layer containing information related to the road network will probably have data for tiles covering large cities, but not for tiles in the middle of the ocean.
