FetchProfile.Item (Java EE 5)

java.lang.Object
  javax.mail.FetchProfile.Item

此内部类是可在 FetchProfile 中请求的所有项的基类。此处目前定义的项是 ENVELOPE、CONTENT_INFO 和 FLAGS。UIDFolder 接口还定义了 UID Item。

注意，此类只有一个受保护的构造方法，因此新的 Item 类型被限制为此类或其子类。这有效地实现了所允许 Item 类型的枚举。

javax.mail.UIDFolder

英文文档：

This inner class is the base class of all items that can be requested in a FetchProfile. The items currently defined here are ENVELOPE, CONTENT_INFO and FLAGS. The UIDFolder interface defines the UID Item as well.

Note that this class only has a protected constructor, therby restricting new Item types to either this class or subclasses. This effectively implements a enumeration of allowed Item types.
