我搜了代碼 找 onBusinessWorkerConnected 在哪里賦值的，結(jié)果沒(méi)找到，只有初始化時(shí)的一個(gè)null

    /**
     * BusinessWorker 連接成功之后觸發(fā)
     *
     * @var callback|null
     */
    public $onBusinessWorkerConnected = null;

我怕自己代碼不是最新的，又搜了下代碼庫(kù)
https://github.com/walkor/GatewayWorker/search?q=onBusinessWorkerConnected
也沒(méi)有找到，

請(qǐng)問(wèn) onBusinessWorkerConnected 這個(gè)屬性是不是沒(méi)有用呢？
