    • Field Detail

      • SIZEOF

        The struct size in bytes.
      • ALIGNOF

        The struct alignment in bytes.

    • Constructor Detail

      • CXType

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