The code for the model element Vehicle is shown in Listing 9. Although the definitions for these interfaces are similar to those of classes, the operations under these interfaces are always abstract.
这个模型元素vehicle的代码显示在列表9中。尽管这些接口的定义与那些类定义十分相似，但是这些接口下面的操作通常是抽象的。
There's also a sample application (see the Downloads section) containing Geronimo GBeans, which abstract the public interfaces of the primary components of the Pluto framework.
还有包含GeronimoGBean的样例应用程序（请参阅下载部分），Geronimo GBean 将用于抽象化Pluto框架的主要组件的公共接口。
In Ada 95 an abstract type could only have one immediate ancestor, but in Ada 2005 it is possible to derive a new type from multiple interfaces or tagged types.
在Ada 95中，一个抽象的类型只能拥有一个即时的起源，但是在Ada 2005中，可能会从标记类型的多种接口中获得一个新的类型。
What's more, com.acme.ascp.billing's abstractness value is 0.8, which indicates it can be shielded from modifications through its interfaces and abstract classes.
此外，com . acme . ascp . billing的抽象性值是0.8，这表明它可以通过接口和抽象类来防止被修改。
Enable consumers and providers to develop against abstract data and service models rather than directly to prescribed interfaces.
允许使用者和提供者以抽象的数据和服务模型(而不是预先确定的接口)为基础进行开发。
Finally, Composite is one of the patterns that can be implemented with an abstract aspect using tag interfaces to specify the classes playing the roles.
最后，组合是可用抽象方面实现的模式之一，可以使用标签接口来规定担任该角色的类。
To port XM to other user interfaces, implement the interfaces such as Messenger (see the previous section) that abstract the user interface.
要将XM 移植到其他界面，只需要像Messenger（请参阅上一节）那样抽象用户界面的接口即可。
The abstract keyword makes using interfaces a lot easier, as I show later.
abstract关键字使得使用接口十分容易，我稍后将加以说明。
That's is the reason abstract methods should be in abstract class (so that one cannot create the object for the abstract class) or interfaces only.
这是抽象的方法应该是抽象类的原因(使人不能创建抽象类的对象)或接口只。
The main advantage in using interfaces is that classes can implement more than one of them, as opposed to being able to derive from a single base class (abstract or otherwise).
使用接口的主要优点是可以实现的类不止一个，而这些类不能从一个单一的基类派生(抽象或相反)。
Why abstract classes instead of interfaces?
为什么抽象类代替了接口？
Avoid abstract methods, use interfaces instead.
