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