toJson method

@override Map<String, dynamic> toJson()

转换为基本数据类型的Map。转换结果可以直接使用jsonEncode进行序列化，可以直接保存到mongo数据库

Implementation

@override
Map<String, dynamic> toJson() {
  final map = <String, dynamic>{};
  $cmds?.forEach((element) {
    map[element._name] = element._cmds.isNotEmpty ? element._cmds : DBUnsupportNullValue('\$cmds', element._name);
  });
  if ($or != null) {
    map['\$or'] = $or!.map((e) => {for (var element in e) element._name: element._cmds.isNotEmpty ? element._cmds : DBUnsupportNullValue('\$or', element._name)}).toList();
  }
  if ($and != null) {
    map['\$and'] = $and!.map((e) => {for (var element in e) element._name: element._cmds.isNotEmpty ? element._cmds : DBUnsupportNullValue('\$and', element._name)}).toList();
  }
  if ($nor != null) {
    map['\$nor'] = $nor!.map((e) => {for (var element in e) element._name: element._cmds.isNotEmpty ? element._cmds : DBUnsupportNullValue('\$nor', element._name)}).toList();
  }
  return map;
}
