MapDataStore 5.46.0

final class · pocketmine\world\map\MapDataStore · source

Saves map data in a folder: one gzip-compressed NBT file per map (map_<id>.dat, vanilla map data tags) and the next free map ID in idcounts.json. Vanilla Bedrock keeps maps in the world LevelDB as map_<id> keys; PocketMine keeps one folder for the whole server (<data>/maps), like PositionTrackingDB, so a map item keeps working in every world.

Methods

__construct()

public function __construct(string $path)

allocateId()

public function allocateId() : int

Returns a new map ID and saves the counter immediately, so that IDs are never handed out twice even if the server crashes.

getPath()

public function getPath() : string

load()

public function load(int $id) : ?\pocketmine\world\map\MapData

Loads the data of a map, or returns null if there is none (or it is corrupted).

save()

public function save(\pocketmine\world\map\MapData $data) : void

wasAllocated()

public function wasAllocated(int $id) : bool

Returns whether the ID was handed out by allocateId() at some point.
