/* From FHIRCommon 4.1.0: */ /* @description: Normalizes a value that is a choice of timing-valued types to an equivalent interval @comment: Normalizes a choice type of FHIR.dateTime, FHIR.Period, FHIR.Timing, FHIR.instance, FHIR.string, FHIR.Age, or FHIR.Range types to an equivalent interval. This selection of choice types is a superset of the majority of choice types that are used as possible representations for timing-valued elements in FHIR, allowing this function to be used across any resource. The input can be provided as a dateTime, Period, Timing, instant, string, Age, or Range. The intent of this function is to provide a clear and concise mechanism to treat single elements that have multiple possible representations as intervals so that logic doesn't have to account for the variability. More complex calculations (such as medication request period or dispense period calculation) need specific guidance and consideration. That guidance may make use of this function, but the focus of this function is on single element calculations where the semantics are unambiguous. If the input is a dateTime, the result a DateTime Interval beginning and ending on that dateTime. If the input is a Period, the result is a DateTime Interval. If the input is a Timing, an error is raised indicating a single interval cannot be computed from a Timing. If the input is an instant, the result is a DateTime Interval beginning and ending on that instant. If the input is a string, an error is raised indicating a single interval cannot be computed from a string. If the input is an Age, the result is a DateTime Interval beginning when the patient was the given Age, and ending immediately prior to when the patient was the given Age plus one year. If the input is a Range, the result is a DateTime Interval beginning when the patient was the Age given by the low end of the Range, and ending immediately prior to when the patient was the Age given by the high end of the Range plus one year. NOTE: Due to the complexity of determining a single interval from a Timing or String type, this function will throw a run-time exception if it is used with a Timing or String. */ define fluent function toInterval(choice Choice<FHIR.dateTime, FHIR.Period, FHIR.Timing, FHIR.instant, FHIR.string, FHIR.Age, FHIR.Range>): case when choice is FHIR.dateTime then Interval[FHIRHelpers.ToDateTime(choice as FHIR.dateTime), FHIRHelpers.ToDateTime(choice as FHIR.dateTime)] when choice is FHIR.Period then FHIRHelpers.ToInterval(choice as FHIR.Period) when choice is FHIR.instant then Interval[FHIRHelpers.ToDateTime(choice as FHIR.instant), FHIRHelpers.ToDateTime(choice as FHIR.instant)] when choice is FHIR.Age then Interval[FHIRHelpers.ToDate(Patient.birthDate) + FHIRHelpers.ToQuantity(choice as FHIR.Age), FHIRHelpers.ToDate(Patient.birthDate) + FHIRHelpers.ToQuantity(choice as FHIR.Age) + 1 year) when choice is FHIR.Range then Interval[FHIRHelpers.ToDate(Patient.birthDate) + FHIRHelpers.ToQuantity((choice as FHIR.Range).low), FHIRHelpers.ToDate(Patient.birthDate) + FHIRHelpers.ToQuantity((choice as FHIR.Range).high) + 1 year) when choice is FHIR.Timing then Message(null as Interval<DateTime>, true, 'NOT_IMPLEMENTED', 'Error', 'Calculation of an interval from a Timing value is not supported') when choice is FHIR.string then Message(null as Interval<DateTime>, true, 'NOT_IMPLEMENTED', 'Error', 'Calculation of an interval from a String value is not supported') else null as Interval<DateTime> end
