# 类: GroupMemberList

[(返回目录)](/api.md)

**继承自:** [GroupAPI](/api/groupapi.md)

RainyBot的群成员列表类，通常代表一个对应实例，储存了某个群组中所有群成员的列表

## 描述

这是RainyBot的群成员列表类，通常代表一个对应实例，储存了某个群组中所有群成员的列表\
你可以像数组/字典一样直接使用for x in x的语法来循环列表中的所有群成员(将返回GroupMember类实例)

## 方法

* static [GroupMemberList](/api/groupmemberlist.md) **init\_meta (** [Array](https://docs.godotengine.org/en/latest/classes/class_array.html) arr **)**

通过机器人协议后端的元数据数组构造一个GroupMemberList类的实例，仅当你知道自己在做什么时才使用

***

* [Array](https://docs.godotengine.org/en/latest/classes/class_array.html) **get\_metadata ( )**

获取实例中的元数据数组，仅当你知道自己在做什么时才使用

***

* void **set\_metadata (** [Array](https://docs.godotengine.org/en/latest/classes/class_array.html) arr **)**

使用指定数组覆盖实例中的元数据数组，仅当你知道自己在做什么时才使用

***

* [GroupMember](/api/groupmember.md) **get\_from\_index (** [int](https://docs.godotengine.org/en/latest/classes/class_int.html) index **)**

根据指定的序号来从群成员列表实例中获取对应的GroupMember实例

若序号不存在则返回null

***

* [GroupMember](/api/groupmember.md) **get\_from\_id (** [int](https://docs.godotengine.org/en/latest/classes/class_int.html) member\_id **)**

根据指定的群成员ID来从群成员列表实例中获取对应的GroupMember实例

若群成员ID不存在则返回null

***

* [bool](https://docs.godotengine.org/en/latest/classes/class_bool.html) **has\_member (** [int](https://docs.godotengine.org/en/latest/classes/class_int.html) member\_id **)**

判断群成员列表实例中是否存在指定ID的群成员实例

***

* [int](https://docs.godotengine.org/en/latest/classes/class_int.html) **get\_size ( )**

获取群成员列表实例中的群成员实例的总数
