Method Details

of

public static StructLayout of(Class<?> recordType)

Packed layout (vertex buffers, CPU-side).

of

public static StructLayout of(Class<?> recordType,
 LayoutMode mode)

Layout with specific mode (PACKED, STD140, STD430).

register

public static void register(Class<?> recordType,
 LayoutMode mode,
 StructLayout layout)

Pre-registers a struct layout, bypassing reflection. Use this for platforms that don't support Class.getRecordComponents() (e.g., TeaVM). Must be called before StructLayout.of() for the same type.

manual

public static StructLayout manual(Class<?> recordType,
 LayoutMode mode,
 List<StructLayout.Field> fields,
 int size,
 StructLayout.WriteFunction writeFunc)

Creates a StructLayout from manually specified fields (no reflection needed). The write function receives (memory, baseOffset, record) and must write all fields relative to the given base offset.

fields

public List<StructLayout.Field> fields()

size

public int size()

mode

public LayoutMode mode()

write

public void write(NativeMemory memory,
 long offset,
 Object record)
