本文整理了Java中com.google.gwt.user.client.Command类的一些代码示例，展示了Command类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Command类的具体详情如下：
包路径：com.google.gwt.user.client.Command
类名称：Command

Command介绍

[英]Encapsulates an action for later execution, often from a different context.

The Command interface provides a layer of separation between the code specifying some behavior and the code invoking that behavior. This separation aids in creating reusable code. For example, a com.google.gwt.user.client.ui.MenuItem can have a Command associated with it that it executes when the menu item is chosen by the user. Importantly, the code that constructed the Command to be executed when the menu item is invoked knows nothing about the internals of the MenuItem class and vice-versa.

The Command interface is often implemented with an anonymous inner class. For example,

Command sayHello = new Command() { 
public void execute() { 
Window.alert("Hello"); 
} 
}; 
sayHello.execute();

This type extends ScheduledCommand to help migrate from DeferredCommand API.
[中]封装操作以供以后执行，通常来自不同的上下文。
命令接口在指定某些行为的代码和调用该行为的代码之间提供了一层分隔。这种分离有助于创建可重用代码。例如，一个com。谷歌。gwt。使用者客户用户界面。MenuItem可以有一个与之关联的命令，当用户选择菜单项时，它将执行该命令。重要的是，构造要在调用菜单项时执行的命令的代码对MenuItem类的内部内容一无所知，反之亦然。
命令接口通常由匿名内部类实现。例如

Command sayHello = new Command() { 
public void execute() { 
Window.alert("Hello"); 
} 
}; 
sayHello.execute();

此类型扩展ScheduledCommand以帮助从DeferredCommand API迁移。
