  • Field Details

    • SIZEOF

      public static final int SIZEOF
      The struct size in bytes.

    • ALIGNOF

      public static final int ALIGNOF
      The struct alignment in bytes.

    • LOW64

      public static final int LOW64
      The struct member offsets.

    • HIGH64

      public static final int HIGH64
      The struct member offsets.

  • Constructor Details

    • XXH128Hash

      public XXH128Hash(ByteBuffer container)
      Creates a XXH128Hash 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<XXH128Hash>

    • low64

      public long low64()
      Returns:
      the value of the low64 field.

    • high64

      public long high64()
      Returns:
      the value of the high64 field.

    • malloc

      public static XXH128Hash malloc()
      Returns a new XXH128Hash instance allocated with memAlloc. The instance must be explicitly freed.

    • calloc

      public static XXH128Hash calloc()
      Returns a new XXH128Hash instance allocated with memCalloc. The instance must be explicitly freed.

    • create

      public static XXH128Hash create()
      Returns a new XXH128Hash instance allocated with BufferUtils.

    • create

      public static XXH128Hash create(long address)
      Returns a new XXH128Hash instance for the specified memory address.

    • createSafe

      public static @Nullable XXH128Hash createSafe(long address)
      Like create, but returns null if address is NULL.

    • malloc

      public static XXH128Hash.Buffer malloc(int capacity)
      Returns a new XXH128Hash.Buffer instance allocated with memAlloc. The instance must be explicitly freed.
      Parameters:
      capacity - the buffer capacity

    • calloc

      public static XXH128Hash.Buffer calloc(int capacity)
      Returns a new XXH128Hash.Buffer instance allocated with memCalloc. The instance must be explicitly freed.
      Parameters:
      capacity - the buffer capacity

    • create

      public static XXH128Hash.Buffer create(int capacity)
      Returns a new XXH128Hash.Buffer instance allocated with BufferUtils.
      Parameters:

      capacity - the buffer capacity

    • createSafe

      public static @Nullable XXH128Hash.Buffer createSafe(long address, int capacity)
      Like create, but returns null if address is NULL.

    • malloc

      public static XXH128Hash malloc(MemoryStack stack)
      Returns a new XXH128Hash instance allocated on the specified MemoryStack.
      Parameters:
