  • Field Details

    • SIZEOF

      public static final int SIZEOF
      The struct size in bytes.

    • ALIGNOF

      public static final int ALIGNOF
      The struct alignment in bytes.

    • FREQUENCY

      public static final int FREQUENCY
      The struct member offsets.

  • Constructor Details

    • spng_hist

      public spng_hist(ByteBuffer container)
      Creates a spng_hist 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_hist>

    • frequency

      public ShortBuffer frequency()
      Returns:
      a ShortBuffer view of the frequency field.

    • frequency

      public short frequency(int index)
      Returns:
      the value at the specified index of the frequency field.

    • frequency

      public spng_hist frequency(ShortBuffer value)
      Copies the specified ShortBuffer to the frequency field.

    • frequency

      public spng_hist frequency(int index, short value)
      Sets the specified value at the specified index of the frequency field.

    • set

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

    • malloc

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

    • calloc

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

    • create

      public static spng_hist create()

      Returns a new spng_hist instance for the specified memory address.

    • createSafe

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

    • malloc

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