Example 1 with Argument

use of org.hl7.fhir.utilities.graphql.Argument in project quality-measure-and-cohort-service by Alvearie.

the class SparkCqlEvaluator method getFilteredRequests.

/**
 * @param requests     Request object to filter.
 * @param libraries    Map of library id to version used for filtering
 *                     down request based on library id. If this argument
 *                     is null or empty, then no library id filtering
 *                     is performed.
 * @param expressions  Used to optionally override which expressions will
 *                     run for each individual CqlEvaluationRequest. If this
 *                     argument is null or empty, no expressions are overwritten.
 *
 * @return CqlEvaluationRequests with the original requests optionally filtered
 *         based on the library ids the.
 *         Requests will optionally have their expressions overridden
 *         by args.expressions. if any are provided.
 *         Individual requests will also will also have any global
 *         parameters set on each individual CqlEvaluationRequest.
