      • resolveByUrl

        protected ValueSet resolveByUrl​(org.opencds.cqf.cql.engine.terminology.ValueSetInfo valueSetInfo)
        Lookup a ValueSet that corresponds to the provided CQL ValueSetInfo. Only the ValueSetInfo.id property is supported at this time. Use of the ValueSetInfo.version or ValueSetInfo.codesystems properties will cause an UnsupportedOperationException. This method uses a search strategy that first treats the ValueSetInfo.id as a URL, then attempts urn:oid or urn:uuid resolution, then finally attempts plain ID-based resolution if nothing has been found and the value appears to be a FHIR ID.
        Parameters:
        valueSet - CQL ValueSetInfo with ID property populated
        Returns:
        resolved ValueSet resource
        Throws:
        java.lang.IllegalArgumentException - if the ValueSetInfo.id could not be resolved
        java.lang.UnsupportedOperationException - if the ValueSetInfo.codesystem property is specified.
