    • Field Detail

      • SIZEOF

        The struct size in bytes.
      • ALIGNOF

        The struct alignment in bytes.

    • Constructor Detail

      • ParSLAnnotation

        public ParSLAnnotation​(java.nio.ByteBuffer container)
        Creates a ParSLAnnotation 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.

        public float u_along_curve()
        Returns the value of the u_along_curve field.
      • v_across_curve

        public float v_across_curve()
        Returns the value of the v_across_curve field.
      • spine_to_edge_x

        public float spine_to_edge_x()
        Returns the value of the spine_to_edge_x field.
      • spine_to_edge_y

        public float spine_to_edge_y()
        Returns the value of the spine_to_edge_y field.
      • create

        public static ParSLAnnotation create​(long address)
        Returns a new ParSLAnnotation instance for the specified memory address.
      • createSafe

        public static ParSLAnnotation createSafe​(long address)
        Like create, but returns null if address is NULL.
      • create

        public static ParSLAnnotation.Buffer create​(long address,
                                                    int capacity)
        Create a ParSLAnnotation.Buffer instance at the specified memory.
        address - the memory address
        capacity - the buffer capacity
      • createSafe
