Method Details

requireBounds

public static void requireBounds(MemorySegment mem,
 int offset)

Checks that the fixed block fits. The per-field getters read without their own bound check, so call this once before reading fields out of an untrusted segment.

getChunkX

public static int getChunkX(MemorySegment mem)

getChunkX

public static int getChunkX(MemorySegment mem,
 int offset)

getChunkZ

public static int getChunkZ(MemorySegment mem)

getChunkZ

public static int getChunkZ(MemorySegment mem,
 int offset)

getImage

@Nullable
public static MapImage getImage(MemorySegment mem)

getImage

@Nullable
public static MapImage getImage(MemorySegment mem,
 int offset)

hasImage

public static boolean hasImage(MemorySegment mem,
 int offset)

toObject

public static MapChunk toObject(MemorySegment mem)

toObject

public static MapChunk toObject(MemorySegment mem,
 int offset)

toObject

public static MapChunk toObject(MemorySegment mem,
 int offset,
 @Nullable
 ReadCursor cursor)

Decodes one MapChunk and reports the end of its encoding through the cursor. The variable block is decoded in field order against a running position, and each offset slot must name that position, so the fields decoded are the bytes walked.

serialize

public int serialize(@Nonnull
 MemorySegment mem,
 int offset)

computeSize

public int computeSize()

clone

public MapChunk clone()

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
