/** is the interface that every driver class must implement.



    <p>
    Each driver should supply a service that implements
    the Driver interface.

    </p>
    <p>The DriverManager will try to load as many drivers as it can
    find, and then for any given connection request, it will ask each
    driver in turn to try to connect to the target URL.

    </p>
    <p>
    It is strongly recommended that each Driver object should be
    small and standalone so that the Driver object can be loaded and
    queried without bringing in vast quantities of supporting code.

        The driver should return
        `NULL`
        if it realizes it is the wrong kind
        of driver to connect to the given URL.  This will be common, as when
        the driver manager is asked to connect to a given URL it passes
        the URL to each loaded driver in turn.



        <p>
        The driver should raise a
        com::sun::star::sdbc::SQLException

        driver to connect to the given URL, but has trouble connecting to
        the database.

        The info argument can be used to pass arbitrary
        string tag/value pairs as connection arguments.

        included in the Properties. For a JDBC driver also the Java class must
        be supplied in the property named JavaDriverClass, and a class path (a
        space-separated list of URLs) needed to locate that class can optionally
        be supplied in a property named JavaDriverClassPath.
        Possible property value names are when supported by the driver:
