    and may need parameter information. For example, the

    bound to a statement which contains parameters, or to a query which is based upon a parametrized
    statement, it needs values to fill in the parameters with actual values when it is being loaded.
    One method to gather these values is calling the XDatabaseParameterListener listeners, which
    can fill them in.</p>
