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.

getWidth

public static int getWidth(MemorySegment mem)

getWidth

public static int getWidth(MemorySegment mem,
 int offset)

getHeight

public static int getHeight(MemorySegment mem)

getHeight

public static int getHeight(MemorySegment mem,
 int offset)

getPalette

@Nullable
public static int[] getPalette(MemorySegment mem)

getPalette

@Nullable
public static int[] getPalette(MemorySegment mem,
 int offset)

getBitsPerIndex

public static byte getBitsPerIndex(MemorySegment mem)

getBitsPerIndex

public static byte getBitsPerIndex(MemorySegment mem,
 int offset)

getPackedIndices

@Nullable
public static byte[] getPackedIndices(MemorySegment mem)

getPackedIndices

@Nullable
public static byte[] getPackedIndices(MemorySegment mem,
 int offset)

hasPalette

public static boolean hasPalette(MemorySegment mem,
 int offset)

hasPackedIndices

public static boolean hasPackedIndices(MemorySegment mem,
 int offset)

toObject

public static MapImage toObject(MemorySegment mem)

toObject

public static MapImage toObject(MemorySegment mem,
 int offset)

toObject

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

Decodes one MapImage 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 MapImage clone()

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
