the class CqlExecutionProvider method evaluate.

/**
 * Evaluates a CQL expression and returns the results as a Parameters resource.
 *
 * @param theRequestDetails   the {@link RequestDetails RequestDetails}
 * @param subject             ***Only Patient is supported as of now*** Subject
 *                            for which the expression will be
 *                            evaluated. This corresponds to the context in
 *                            which the expression will be evaluated and is
 *                            represented as a relative FHIR id (e.g.
 *                            Patient/123), which establishes both the context
 *                            and context value for the evaluation
 * @param expression          Expression to be evaluated. Note that this is an
 *                            expression of CQL, not the text of a library with
 *                            definition statements.
 * @param parameters          Any input parameters for the expression.
 *                            {@link Parameters} Parameters defined in this
 *                            input will be made available by name to the CQL
 *                            expression. Parameter types are mapped to CQL as
 *                            specified in the Using CQL section of the CPG
 *                            Implementation guide. If a parameter appears more
 *                            than once in the input Parameters resource, it is
 *                            represented with a List in the input CQL. If a
 *                            parameter has parts, it is represented as a Tuple
 *                            in the input CQL.
 * @param library             A library to be included. The {@link Library}
 *                            library is resolved by url and made available by
 *                            name within the expression to be evaluated.
 * @param useServerData       Whether to use data from the server performing the
 *                            evaluation. If this parameter is true (the
 *                            default), then the operation will use data first
 *                            from any bundles provided as parameters (through
 *                            the data and prefetch parameters), second data
 *                            from the server performing the operation, and
 *                            third, data from the dataEndpoint parameter (if
 *                            provided). If this parameter is false, the
 *                            operation will use data first from the bundles
 *                            provided in the data or prefetch parameters, and
 *                            second from the dataEndpoint parameter (if
 *                            provided).
 * @param data                Data to be made available to the library
 *                            evaluation. This parameter is exclusive with the
 *                            prefetchData parameter (i.e. either provide all

 *                            multiple bundles with prefetch descriptions).
 * @param prefetchData        ***Not Yet Implemented***
 * @param dataEndpoint        An {@link Endpoint} endpoint to use to access data
 *                            referenced by retrieve operations in the library.
 *                            If provided, this endpoint is used after the data
 *                            or prefetchData bundles, and the server, if the
 *                            useServerData parameter is true.
 * @param contentEndpoint     An {@link Endpoint} endpoint to use to access
 *                            content (i.e. libraries) referenced by the
 *                            library. If no content endpoint is supplied, the
 *                            evaluation will attempt to retrieve content from
 *                            the server on which the operation is being
 *                            performed.
 * @param terminologyEndpoint An {@link Endpoint} endpoint to use to access
 *                            terminology (i.e. valuesets, codesystems, and
 *                            membership testing) referenced by the library. If
 *                            no terminology endpoint is supplied, the
 *                            evaluation will attempt to use the server on which

 *                            terminology server.
 * @return The result of evaluating the given expression, returned as a FHIR
 *         type, either a {@link Resource} resource, or a FHIR-defined type
 *         corresponding to the CQL return type, as defined in the Using CQL
