| 1. | The application requires access to intermediate data states
应用程序需要访问中间数据状态。 |
| 2. | Like a closure , a generator " remembers " the state of its data
象“终止”一样，生成器“记住”了它数据状态。 |
| 3. | The application requires net data change rather than access to intermediate data states
应用程序需要最终的数据更改结果，而不是访问中间数据状态。 |
| 4. | This is useful when the client wants to display the status of data being received from the server
这在客户端需要显示从服务器接收到的数据状态时很有用。 |
| 5. | Applications using query notifications do not have to periodically verify the state of the data in the database
使用查询通知的应用程序不必定期验证数据库中的数据状态。 |
| 6. | As you can see , koh is more or less like dkom , except that it uses call hooks instead of data - state changes
可以看到， koh除了它使用调用挂钩代替数据状态的改变之外，多多少少与dkom类似。 |
| 7. | If an iterator class or a function with static or global variables depends on multiple data states , two problems come up
如果带静态（或全局）变量的迭代器类或函数取决于多个数据状态，则出现两个问题。 |
| 8. | The far more important problem is figuring out how to get back to exactly the relevant part of the flow logic that corresponds to the data states
更为重要的问题是计算如何确切地返回到与数据状态相符的流逻辑的相关部分。 |
| 9. | Breakpoints are places in the code where the debugger will stop the application , allow you to view the current data state of the application , and then step through each line of code
断点是代码中调试器将要停止应用程序的位置，您可以使用断点查看应用程序的当前数据状态，然后逐句通过每一行代码。 |
| 10. | To reflect these policies dictating the currency of the data , the udm allows the cache to be either explicitly managed for example , a schedule could be defined to refresh the cache daily at 2 a . m . or transparently managed by using proactive caching
为了反映这种指定数据状态的策略， udm既允许显式管理缓存（例如，可以将计划定义为在每天凌晨2点刷新缓存） ，也允许使用“主动缓存”进行透明管理。 |
