Aggregating allows any number of extensions to be added, without the need for defining all possible combinations of subclasses.

聚合允许添加任意数量的扩展，而无需定义子类的所有可能的组合。

Note that type definitions for classes Order and Item appear in the schema, but type definitions for the subclasses of Item do not.

注意模式中有Order及Item类的类型定义，但是没有Item的子类的类型定义。

You can then use the base class, or any of the subclasses, in methods that are typed to expect the base class as a method argument.

然后您就可以在键入的以基类作为方法参数的方法中使用基类或任何一个子类。

It is also very easy to modify superclasses and add new subclasses because you merely need to modify or add one table.

修改超类和添加新的子类也非常容易，因为您只需要修改或添加一张表。

Further, since the response types are correct, the response contains the additional elements of the Item subclasses.

而且，由于响应类型是正确的，所以响应包含Item子类的附加元素。

Qualified subclass name: Name subclasses to communicate the similarities and differences with a superclass.

子类名称要合格：对子类的命名会表述出其与超类之间的相似和差异之处。

You certainly can provide optimized implementations of these methods in your subclasses, but you don't have to.

当然可以在子类中提供这些方法的优化实现，但是不是必须这么做。

Value indicating whether the qualifier should be propagated to subclasses of the class.

值，该值指示是否应将限定符传播给类的子类。

Gets or sets a value indicating whether the qualifier should be propagated to subclasses of the class.

获取或设置一个值，该值指示是否将限定符传播给类的子类。

Hibernate returns a collection of the matching heterogeneous concrete subclasses automatically when an abstract class is queried.

当查询抽象类时，Hibernate会自动返回一个集合，由匹配的具体异构子类构成。

Ontologies define data models in terms of classes, subclasses, and properties.

存在论用类、子类和属性来定义数据模型。

It has a protected modifier, so it's only available to derived subclasses and within the Lure class itself.

它具有一个受保护的修饰符，所以它只对派生子类可用并且在Lure类本身的内部。

Template Method lets subclasses redefine certain steps of an algorithm without changing the algorithm's structure.

模板方法使得子类可以不改变一个算法的结构即可重定义该算法的某些特定步骤。

This approach provided an easy way of adding new subclasses for different types of external communication at later stages in the project.

在项目的后续阶段中，这提供了一种简单的方法，为不同类型的外部通信添加新的子类。

The View class serves as the base for subclasses called "widgets, " which offer fully implemented UI objects, like text fields and buttons.

View类是它称为“widgets（工具）”的子类的基础，它们提供了诸如文本输入框和按钮之类的UI对象的完整实现。
