Functions

addCurrentSnapshotUser

Timestamp addCurrentSnapshotUser(ChunkWorldPos cwp)

Returns timestamp of current chunk snapshot. Store this timestamp to use in removeSnapshotUser

commitSnapshots

void commitSnapshots(Timestamp currentTime)

called at the end of tick

getChunkSnapshot

Nullable!ChunkDataSnapshot getChunkSnapshot(ChunkWorldPos cwp)

returned value isNull if chunk is not loaded/added

getWriteBuffer

BlockId[] getWriteBuffer(ChunkWorldPos cwp)

Returns writeable copy of current chunk snapshot. Any changes made to it must be reported trough onBlockChanges method. This buffer is valid until commit. After commit this buffer becomes next immutable snapshot. Returns null if chunk is not added and/or not loaded.

onBlockChanges

void onBlockChanges(ChunkWorldPos cwp, R blockChanges)

Call this whenewer changes to write buffer are done. Those changes will be passed to chunkChangesHandlers to be handled when sendChanges is called.

onSnapshotLoaded

void onSnapshotLoaded(ChunkWorldPos cwp, ChunkDataSnapshot snap)

Internal. Called by code which loads chunks from storage.

onSnapshotSaved

void onSnapshotSaved(ChunkWorldPos cwp, ChunkDataSnapshot savedSnap)

Internal. Called by code which saves chunks to storage.

removeSnapshotUser

void removeSnapshotUser(ChunkWorldPos cwp, Timestamp timestamp)

Generic removal of snapshot user. Removes chunk if numUsers == 0. Use this to remove added snapshot user. Use timestamp returned from addCurrentSnapshotUser.

save

void save()

Performs save of all modified chunks. Modified chunks

sendChanges

void sendChanges()

Send changes to clients

setExternalChunkUsers

void setExternalChunkUsers(ChunkWorldPos cwp, size_t numExternalUsers)

Sets number of users of chunk at cwp. If total chunk users if greater than zero, then chunk is loaded, if equal to zero, chunk will be unloaded.
