| 1. | You need to generate unique values for the surrogate key
首先需要为代理键生成惟一的值。 |
| 2. | Save your files and press f5 to build and launch your project
保存文件，并按f5键生成和启动项目。 |
| 3. | The key manager encapsulates the surrogate key generation function
键管理器封装了代理键生成函数。 |
| 4. | You can put the surrogate key generation function in the insert statement
您可以在insert语句中实现代理键生成函数： |
| 5. | It focused on how to generate unique consequent values for the surrogate key
文中主要讨论了如何为代理键生成惟一的序列值。 |
| 6. | Object to use to determine whether two keys are equal and to generate hash codes for the keys in the collection
对象，用于确定两个键是否相等，并为集合中的键生成哈希代码。 |
| 7. | In order to make the generation of the cache keys reusable for individual projects , separate the key generation into its own class
为了生成可供各个项目重用的缓存键，可以将键生成分类。 |
| 8. | Then , you look at a second cache key generation technique to address the need for caching data that is private to a portlet window
然后，您将了解第二个缓存键生成技术，它可以满足缓存专用于portlet窗口的数据的要求。 |
| 9. | Next , let s look at an example that uses both key generation mechanisms and stores the data using the dynacache infrastructure
接下来，我们看一个示例，它使用了这两种键生成机制，并且通过dynacache基础设施存储数据。 |
| 10. | It is possible for a hash function to generate the same hash code for two different keys , but a hash function that generates a unique hash code for each unique key results in better performance when retrieving elements from the hash table
一个哈希函数能够为两个不同的键生成相同的哈希代码，但从哈希表检索元素时，为每一唯一键生成唯一哈希代码的哈希函数将令性能更佳。 |
