EventBus 黏性事件的postSticky

    /**
     * Posts the given event to the event bus and holds on to the event (because it is sticky). The most recent sticky
     * event of an event's type is kept in memory for future access by subscribers using {@link Subscribe#sticky()}.
     */
    public void postSticky(Object event) {
        synchronized (stickyEvents) {
            stickyEvents.put(event.getClass(), event);
        }
        // Should be posted after it is putted, in case the subscriber wants to remove immediately
        post(event);
    }

将事件类型添加到stickyEvents中，是一个Map，Key是事件类型，Value是事件对象；

然后调用post方法；对已经注册过得方法发送订阅事件；

这里我有一点疑惑，就是这个注释：

// Should be posted after it is putted, in case the subscriber wants to remove immediately

翻译过来就是：在put到stickyEvents之后应该立即post出去，防止订阅者想要立刻移除事件；

没明白是什么意思…
