UI.push介绍

[英]Pushes the pending changes and client RPC invocations of this UI to the client-side.

If push is enabled, but the push connection is not currently open, the push will be done when the connection is established.

As with all UI methods, the session must be locked when calling this method. It is also recommended that UI#getCurrent() is set up to return this UI since writing the response may invoke logic in any attached component or extension. The recommended way of fulfilling these conditions is to use #access(Runnable).
[中]将此UI的挂起更改和客户端RPC调用推送到客户端。
如果已启用推送，但推送连接当前未打开，则推送将在连接建立后完成。
与所有UI方法一样，调用此方法时必须锁定会话。还建议将UI#getCurrent（）设置为返回此UI，因为编写响应可能会调用任何附加组件或扩展中的逻辑。满足这些条件的推荐方法是使用#访问（Runnable）。
