$compareFireRating

Compares two fields that should contain the same fire rating value — the built-in Revit Fire Rating type parameter and the shared parameter NLRS_C_brandwerendheid. Returns a consistency object for use with the applicability gate pattern.

---

Definition

$compareFireRating := function($fireRating, $nlrs){
  (
    $fireExists := $exists($fireRating) and $fireRating != null;
    $nlrsExists := $nlrs.paramExist and $nlrs.value != "Parameter niet aanwezig";

    $fireVal := $fireExists ? $string($fireRating) : "";
    $nlrsVal := $nlrsExists ? $string($nlrs.value) : "";

    {
      "checkApplicable": $fireExists and $nlrsExists,
      "fireRatingValue": $fireVal,
      "nlrsValue":       $nlrsVal,
      "isEqual":         ($fireExists and $nlrsExists)
                           ? ($fireVal = $nlrsVal)
                           : true
    }
  )
};

---

Parameters

Parameter	Type	Description
$fireRating	any	The value of values.fireRating from the current element
$nlrs	object	The result of $getSharedParam($, "NLRS_C_brandwerendheid")

---

Return value

{
  "checkApplicable": true,
  "fireRatingValue": "60",
  "nlrsValue": "30",
  "isEqual": false
}

When one of the two values is absent, checkApplicable is false and isEqual defaults to true — the rule does not fire for elements where the comparison cannot be made.

---

Usage

$[type = "FamilySymbol" and values.category.type = "Model"].{
  "id": id,
  "name": name,
  "fireRating": values.fireRating,
  "NLRS_C_brandwerendheid": $getSharedParam($, "NLRS_C_brandwerendheid"),
  "fireRatingConsistency": $compareFireRating(
    values.fireRating,
    $getSharedParam($, "NLRS_C_brandwerendheid")
  )
}
[fireRatingConsistency.checkApplicable]

The [fireRatingConsistency.checkApplicable] at the end is the applicability gate — elements where neither field is filled are excluded from the result.

Validators access:

• fireRatingConsistency.isEqual → bool:Is true
• fireRatingConsistency.fireRatingValue → list:IsIn [0, 30, 60, 90, 120]
• fireRatingConsistency.nlrsValue → list:IsIn [0, 30, 60, 90, 120]
