call method

FutureOr call(DoxRequest req)

Fill the parameters for req and call the controller. A path param that does not fit its type answers 404. Without a DTO it is sync and gives what the controller gives.

Implementation

FutureOr<dynamic> call(DoxRequest req) {
  int count = args.length;
  if (count == 1 && args[0].kind == ArgKind.request) {
    return fn(req);
  }
  List<dynamic> values = List<dynamic>.filled(count, null);
  ControllerArg? dtoArg;
  int dtoIndex = -1;
  for (int i = 0; i < count; i++) {
    ControllerArg arg = args[i];
    switch (arg.kind) {
      case ArgKind.request:
        values[i] = req;
      case ArgKind.path:
        values[i] = _path(arg, req.param[arg.param]);
      case ArgKind.dto:
        dtoArg = arg;
        dtoIndex = i;
    }
  }
  // path params first: when one is wrong, the DTO is not checked
  if (dtoArg != null) return _callWithDto(req, dtoArg, dtoIndex, values);
  return _apply(values);
}
