在第一次调用,num等于10时函数的值尚未缓存,if 语句num in cache返回false,else 块的代码被执行:Calculated! 20,并且其结果被添加到缓存对象,cache现在看起来像{10:20}。 第二次,cache对象包含10的返回值。if 语句 num in cache 返回true,From cache! 20被打印。 第三次,我们将5 * 2(值为 10) 传递给...

Map services contain one or more sublayers. Sublayers may even contain nested sublayers. When the sublayers property of the MapImageLayer is not specified, then an image of all sublayers in the service is exported to the client. If a subset of sublayers from the service are specified, th...
