# NoneBot.handler 模块
## 事件处理函数
该模块实现事件处理函数的封装,以实现动态参数等功能。
## _class_ `Handler`
基类:`object`
事件处理函数类
### `__init__(func)`
装饰事件处理函数以便根据动态参数运行
### `func`
* **类型**
`T_Handler`
* **说明**
事件处理函数
### `signature`
* **类型**
`inspect.Signature`
* **说明**
事件处理函数签名
### _property_ `bot_type`
* **类型**
`Union[Type["Bot"], inspect.Parameter.empty]`
* **说明**
事件处理函数接受的 Bot 对象类型
### _property_ `event_type`
* **类型**
`Optional[Union[Type[Event], inspect.Parameter.empty]]`
* **说明**
事件处理函数接受的 event 类型 / 不需要 event 参数
### _property_ `state_type`
* **类型**
`Optional[Union[T_State, inspect.Parameter.empty]]`
* **说明**
事件处理函数是否接受 state 参数
### _property_ `matcher_type`
* **类型**
`Optional[Union[Type["Matcher"], inspect.Parameter.empty]]`
* **说明**
事件处理函数是否接受 matcher 参数
