接下来的例子演示了Flex中通过和Security类中的常量（LOCAL_TRUSTED, LOCAL_WITH_FILE, LOCAL_WITH_NETWORK以及REMOTE）对比sandboxType属性，检查应用程序当前安全沙盒设置。
下面是完整代码:

代码如下:

        <![CDATA[  
            private function init():void {  
                switch (Security.sandboxType) {  
                    case Security.LOCAL_TRUSTED:  
                        sandboxLabel.text += " (Local trusted)";
