      • resolveByUrl

        public void resolveByUrl​(org.opencds.cqf.cql.engine.terminology.ValueSetInfo valueSet)
        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
        Throws:
        java.lang.UnsupportedOperationException - if the ValueSetInfo.codesystem property is specified.
        java.lang.IllegalArgumentException - if zero or more than one ValueSet were resolved for the specified ValueSetInfo.id property.
