     struct parsl_position {
         float x;
         float y;
     }
    • Field Detail

      • SIZEOF

        The struct size in bytes.
      • ALIGNOF

        The struct alignment in bytes.
      • X, Y

        The struct member offsets.
    • Constructor Detail

      • ParSLPosition

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

        Returns a new ParSLPosition instance for the specified memory address.
      • createSafe

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

        public static ParSLPosition.Buffer create​(long address,

        Create a ParSLPosition.Buffer instance at the specified memory.
        Parameters:
        address - the memory address
        capacity - the buffer capacity
      • createSafe
