Class CXVersion

  • All Implemented Interfaces:
    Pointer

    public class CXVersion
    extends Struct
    Describes a version number of the form major.minor.subminor.

    Member documentation

    • Major – the major version number, e.g., the '10' in '10.7.3'. A negative value indicates that there is no version number at all.
    • Minor – the minor version number, e.g., the '7' in '10.7.3'. This value will be negative if no minor version number was provided, e.g., for version '10'.
    • Subminor – the subminor version number, e.g., the '3' in '10.7.3'. This value will be negative if no minor or subminor version number was provided, e.g., in version '10' or '10.7'.

    • Constructor Detail

      • CXVersion

        public CXVersion​(java.nio.ByteBuffer container)
        Creates a CXVersion 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 static CXVersion create​(long address)
        Returns a new CXVersion instance for the specified memory address.
      • createSafe

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

        public static CXVersion.Buffer create​(long address,
                                              int capacity)
        Create a CXVersion.Buffer instance at the specified memory.
        Parameters:
        address - the memory address
