任 何需要存储的类必须是可存储的(PersistenceCapable),而任何用到这些 类的其它类必须是存储可知的(PersistenceAware)。在JDO的透明存储技 术的支持下,开发者只需要像往常一样写一个类,然后为需要存储的类编 写的XML格式的描述进行存储的映射。

滚动到uart行,在Base Address字段中输入0xa0000000(这是刚删除的16550 UART的默认地址,因此可知这是存储小uart的安全位置)。
Scroll to your UART's line, and enter 0xa0000000 in the Base address field (this was the default address for the 16550 UART you just deleted, so you know it's a safe place to put the lite UART).
已经说过,即便如此,我会尽量保持它的用户界面技术不可知论者通过存储作为AGRB值而不是一个不同的颜色。
Having said that, even then I would try to keep it UI-technology agnostic by storing colours as AGRB values instead of one of the various.
