wallsInDocument function

({WorldWall host, List<WorldWall> walls})? wallsInDocument(DraftDocument doc, Handle host, { Map<Handle, WorldWall> moved = const {}, })

The walls the tools, the grips and the panel see around host (the document adapter, Ruling 08-8): host as a WorldWall, and every other live wall of doc (the engine's object rule, asked through live_objects.dart: a file's group that also carries a later-registered type is that type's object, not a wall), ascending by handle. The view adapter (wallsInView) sees only host's neighbours; classify, cap and obstaclesOf ignore a wall that does not join host, so the extra walls change nothing (HF7 pins that both give the same bits). Null when host is not a live wall.

moved stands in for the walls it names (an end drag's walls before it is executed, spec 08 D13): each is read from it instead of doc.

Implementation

({WorldWall host, List<WorldWall> walls})? wallsInDocument(
    DraftDocument doc, Handle host,
    {Map<Handle, WorldWall> moved = const {}}) {
  if (!isLiveObject<WallParams>(doc, host)) return null;
  final p = doc.components.get<WallParams>(host)!;
  return (
    host:
        moved[host] ?? WorldWall(host, p, doc.tree.accumulatedTransform(host)),
    walls: [
      for (final h in liveObjectsOf<WallParams>(doc))
        if (h != host)
          moved[h] ??
              WorldWall(h, doc.components.get<WallParams>(h)!,
                  doc.tree.accumulatedTransform(h)),
    ],
  );
}
