子类型所继承的属性来自哪个类型，该类型就被认为是这个子类型的超类型。
The type from which a subtype inherits attributes is known as its supertype.
DTLL支持类型成分的继承(超类型)，以及其他支持数据类型库模块化和重用的特性。

一些实体具有某些共同的属性，比如标识符(主键)，而其他属性不同，这些实体可能具有共同的超类型。

规范化决定在逻辑数据模型中得以完成，并导致实体-实体关系与超类型-子类型层次关系的最终规范化表示。
Normalization decisions are finalized in the logical data model resulting in the final normalized representation of entity-to-entity relationships as well as supertype-to-subtype hierarchies.
再次按下Ctrl +t,QuickType Hierarchy将在列表中显示超类型(参见图8)。
Press Ctrl + t again, and the Quick type Hierarchy displays the supertypes in the list (see Figure 8).
您也许认为这一原理同样适用于泛型类型——List是List的超类型，那么可以在需要List的地方传递List。
You might think the same is true of generic types as well — that List is a supertype of List, and that you can pass a List where a List is expected.
XMLStreamReader接口基本上定义了基于指针的API（虽然标记常量在其超类型 XMLStreamConstants 接口中定义）。
The XMLStreamReader interface essentially defines the cursor-based API (though the token constants are defined in its super-type, interface XMLStreamConstants).

This table represents a superset of all parameters for all types of supported binding.
清单2 中的字段和方法签名利用了与超接口签名相同的变量格式类型，其他都与前面介绍的内容相同。
The field and method signatures from Listing 2 make use of the same type of variable format as seen in the superinterface signature, but aside from that, they don't show anything new.

By smashing particles together at close to light speed inside an atom smasher, scientists created a never-before-seen type of matter: an anti-hypertriton.
我有很多Scrum的经验，感觉用它来管理各种类型的项目都超好。
I've got lots of experience with Scrum and it is a fantastic way to run many types of projects.
对于超类，您可以引用“core”方案之中“Unit”或者“SoftwareComponent”定义的通用类型，或者您可以引用另一种预定义域中更特定的单元。
For the supertype, you can refer to the general types "unit" or "SoftwareComponent" defined in the "core" schema, or you can refer to a more specific unit in another predefined domain.
注意：如果 com.ibm.collaboration.realtime.messages.MessageHandlerAdapter没有列于超类中，单击Browse并在文本框中输入 MessageHandlerAdapter，以选择类型。
NOTE: If com.ibm.collaboration.realtime.messages.MessageHandlerAdapter is not listed as the superclass click Browse and type in MessageHandlerAdapter in the text box for Choose a type.
但是在我们对超类所知的一切只限于它是类型参数的实例化时，对于什么样的构造函数可用于给定的实例化，我们没有任何概念。
But when all we know about our superclass is that it's some instantiation of a type parameter, we have no idea what constructors will be available for a given instantiation.
通常，通过查找超类并确保存在匹配的超级构造函数，类型检查器确保这些超级构造函数调用会成功。
Normally, the type checker ensures that these super-constructor calls will succeed by looking up the superclass and making sure that a matching super-constructor exists.
因此，当类型参数t用作泛型类的超类时，T的注释确切地告知我们可以调用哪些超级构造函数。
Thus, when a type parameter t is used as the superclass of a generic class, the annotation on t tells us exactly what super-constructors we can call.
换一种说法，如果新类型的可能值是旧类型的超集，那么您就已经对类型进行了扩展。
In other words, if the set of possible values of the new type is a superset of that of the old type, then you have expanded the type.
与对应的无类型超接口相反。
幻灯片的超系列提供了任何类型的竞争力下滑的最长的行程。
The Ultra Series slide offers the longest stroke of any competitive slide of its type.
