  • Field Details

    • SIZEOF

      public static final int SIZEOF
      The struct size in bytes.

    • ALIGNOF

      public static final int ALIGNOF
      The struct alignment in bytes.

    • LENGTH

      public static final int LENGTH
      The struct member offsets.

    • DATA

      public static final int DATA
      The struct member offsets.

  • Constructor Details

    • spng_exif

      public spng_exif(ByteBuffer container)
      Creates a spng_exif instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.

  • Method Details

    • sizeof

      public int sizeof()
      Description copied from class: Struct
      Returns sizeof(struct).
      Specified by:
      sizeof in class Struct<spng_exif>

    • length

      public long length()
      Returns:
      the value of the length field.

    • data

      public ByteBuffer data()
      Returns:
      a ByteBuffer view of the data pointed to by the data field.

    • data

      public spng_exif data(ByteBuffer value)
      Sets the address of the specified ByteBuffer to the data field.

    • set

      public spng_exif set(spng_exif src)
      Copies the specified struct data to this struct.
      Parameters:
      src - the source struct
      Returns:
      this struct

    • malloc

      public static spng_exif malloc()
      Returns a new spng_exif instance allocated with memAlloc. The instance must be explicitly freed.

    • calloc

      public static spng_exif calloc()
      Returns a new spng_exif instance allocated with memCalloc. The instance must be explicitly freed.

    • create

      public static spng_exif create()
      Returns a new spng_exif instance allocated with BufferUtils.

    • create

      public static spng_exif create(long address)
      Returns a new spng_exif instance for the specified memory address.

    • createSafe

      public static @Nullable spng_exif createSafe(long address)
      Like create, but returns null if address is NULL.

    • malloc

      public static spng_exif.Buffer malloc(int capacity)
      Returns a new spng_exif.Buffer instance allocated with memAlloc. The instance must be explicitly freed.
      Parameters:
      capacity - the buffer capacity

    • calloc

      public static spng_exif.Buffer calloc(int capacity)
      Returns a new spng_exif.Buffer instance allocated with memCalloc. The instance must be explicitly freed.
