|      类型       | 描述                                               | 最低支持的版本 |
|:--------------:|:---------------------------------------------------|:-----------:|
| `ContactOrBot` | `Contact` 和 `Bot` 的公共接口                        |     2.0     |
| `OtherClient`  | Bot 的*其他客户端*, 如 "我的 iPad", "我的电脑"          |     2.0     |
|     `Bot`      | 机器人对象                                           |     2.0     |
|   `Contact`    | 联系人对象, 即所有的群, 好友, 陌生人, 群成员等            |     2.0      |
|    `Group`     | 群对象                                              |     2.0     |
|     `User`     | 用户对象, 即 "个人". 包含好友, 陌生人, 群成员, 临时会话用户 |     2.0     |
|    `Friend`    | 好友对象                                            |     2.0      |
|   `Stranger`   | 陌生人对象                                           |     2.0     |
|    `Member`    | 群成员对象, 属于一个 `Group`.                         |     2.0      |

基于面向对象的设计，可直接获取 `Contact` 的属性如 `nick`，`permission`。请在实践时在接口源码内查看更清晰的说明。

要主动发送一条消息，总是调用 `Contact.sendMessage(message)`*（`message` 在后文介绍）*。

可通过 `Bot.getFriend`， `Bot.getGroup`，`Bot.getStranger` 获取相关对象，也可以通过事件获取 *（事件在后文介绍）*。
