package com.quyunshuo.androidbaseframemvvm.base.utils
/**
* 辅助注册 EventBus 的注解
*
* - **使用方式：**
* 在基类中的 `onCreate()`、`onDestroy()` 生命周期回调中去判断当前 Class 对象是否使用了该注解，
* 然后根据结果去注册或反注册
*
* - **为什么不统一注册：**
* 统一注册会在 EventBus 内部集合中留存，每次发送事件时，会遍历集合，过多无用的注册会导致速度变慢，
* 所以最好的方式就是根据需要进行注册，避免无意义的全部注册
*
* - **sample:**
* ```
* abstract class BaseActivity : AppCompatActivity() {
*
* // 是否有 [RegisterEventBus] 注解 ， 避免重复调用 [Class.isAnnotation]
* private var mHaveRegisterEventBus = false
* override fun onCreate(savedInstanceState: Bundle?) {
* super.onCreate(savedInstanceState)
* // 根据子类是否有 RegisterEventBus 注解決定是否进行注册 EventBus
* if (javaClass.isAnnotationPresent(RegisterEventBus::class.java)) {
* mHaveRegisterEventBus = true
* EventBusUtils.register(this)
* }
* }
*
* override fun onDestroy() {
* // 根据子类是否有 RegisterEventBus 注解决定是否进行注册 EventBus
* if (mHaveRegisterEventBus) {
* EventBusUtils.unRegister(this)
* }
* super.onDestroy()
* }
* }
*
* // 子类：
* @RegisterEventBus
* class SampleActivity : BaseActivity()
* ```
