## IRtcEngineEvent [#irtcengineevent]

[IRtcEngineEvent](/zh-CN/api-reference/rtc/electron/rtc-interface-class#class_irtcengineevent) 接口，用于合并 [IRtcEngine](/zh-CN/api-reference/rtc/electron/rtc-interface-class#class_irtcengine) 对象的相关事件接口。

<a id="class_irtcengineevent__detailed_desc"></a>

该接口合并了以下接口：

- [IRtcEngineEventHandler](/zh-CN/api-reference/rtc/electron/rtc-interface-class#class_irtcengineeventhandler)
- `IDirectCdnStreamingEventHandler`
- [IMetadataObserver](/zh-CN/api-reference/rtc/electron/rtc-interface-class#class_imetadataobserver)
- [IAudioEncodedFrameObserver](/zh-CN/api-reference/rtc/electron/rtc-interface-class#class_iaudioencodedframeobserver)
- [IAudioSpectrumObserver](/zh-CN/api-reference/rtc/electron/rtc-interface-class#class_iaudiospectrumobserver)

你可以调用 [addListener](/zh-CN/api-reference/rtc/electron/initialize#api_irtcengine_addlistener), [removeListener](/zh-CN/api-reference/rtc/electron/initialize#api_irtcengine_removelistener) 和 [removeAllListeners](/zh-CN/api-reference/rtc/electron/initialize#api_irtcengine_removealllisteners) 方法来添加监听或取消监听上述接口下的回调事件。

<a id="class_irtcengineeventhandler"></a>

<a id="ariaid-title28"></a>

## IRtcEngineEventHandler [#irtcengineeventhandler]

接口类 [IRtcEngineEventHandler](/zh-CN/api-reference/rtc/electron/rtc-interface-class#class_irtcengineeventhandler) 用于 SDK 向 App 发送事件通知，App 通过继承该接口类的方法获取 SDK 的事件通知。

<a id="class_irtcengineeventhandler__detailed_desc"></a>

该接口类的所有方法都有缺省（空）实现， App 可以根据需要只继承关心的事件。

:::note
注：

- 在回调方法中，App 不应该做耗时或者调用可能会引起阻塞的 API（如 `sendMessage`），否则可能影响 SDK 的运行。
- SDK 不再捕获开发者在 [IRtcEngineEventHandler](/zh-CN/api-reference/rtc/electron/rtc-interface-class#class_irtcengineeventhandler) 类回调中自行实现的代码逻辑中的异常。你需要自行处理该异常，否则异常出现时可能引起 App 崩溃。
