updateByJson method

  1. @override
void updateByJson(
  1. Map<String, dynamic> map, {
  2. Metadata? parser,
})

通过基本数据类型的Map来更新字段。来源map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
void updateByJson(Map<String, dynamic> map, {Metadata? parser}) {
  parser = parser ?? Metadata.fromJson(map);
  if (map.containsKey('_id')) _id = parser._id;
  if (map.containsKey('_bsid')) _bsid = parser._bsid;
  if (map.containsKey('_time')) _time = parser._time;
  if (map.containsKey('_extra')) _extra = parser._extra;
  if (map.containsKey('_trans')) _trans = parser._trans;
  if (map.containsKey('uid')) uid = parser.uid;
  if (map.containsKey('type')) type = parser.type;
  if (map.containsKey('path')) path = parser.path;
  if (map.containsKey('size')) size = parser.size;
  if (map.containsKey('removed')) removed = parser.removed;
}
