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
* data as a single bundle, or provide data using
* 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
* the operation is being performed as the
* 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
* section of the CPG Implementation guide. If the result is a List of
* resources, the result will be a {@link Bundle} Bundle . If the result
* is a CQL system-defined or FHIR-defined type, the result is returned
* as a {@link Parameters} Parameters resource
