    To provide evaluation feature for your engine, your must override this method to return data for evaluation from a data source.

    To provide evaluation feature for your engine, your must override this method to return data for evaluation from a data source. Returned data can optionally include a sequence of query and actual value pairs for evaluation purpose.

    The default implementation returns an empty sequence as a stub, so that an engine can be compiled without implementing evaluation.
