In C#, these are called sealed classes. You can use the keyword <code>sealed</code> to indicate that a class is not to be inherited from. VB uses the keyword <code>NotInheritable</code>. Wikipedia calls them <a href="http://en.wikipedia.org/wiki/Sealed_class#Non-subclassable" rel="nofollow">non-subclassable</a>.

I sealed class doesn't have to inherit from anything. To me the opposite of a base class would be a derived class, but being a derived class doesn't preclude it from being inherited from.

But it sounds like Carl T.'s answer is probably what you were looking for.

blocks|key|5216843|text|基类是一个相对的术语。它仅适用于考虑其派生类之一的情况。下面是我认为对立面的一些术语(它们之间大部分是正交的)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5216844|5216845|基类vs派生类；类似的超类vs子类|unordered-list-item|5216846|抽象类vs具体类|5216847|根类vs叶子类|5216848|密封(也是，最终)类vs可继承(非密封)类|5216849|<代码>H19嵌套类vs顶级类<代码>H210<代码>F211|5216850|抽象类和(通常)根类被设计为基类。密封类不能是基类，因为它们是不可继承的。根类是没有基类的类(在C#和Java中，这个类是Object)。叶子类没有子类，所以它不是基类；但它不一定是密封的。另一方面，密封类始终是叶类。|offset|length|style|CODE|5216851|所以,|5216852|5216853|我正在查找尚未子类化的类的名称|blockquote|5216854|5216855|5216856|看起来您正在寻找一个叶类，，但我不认为它是基类的对立面。|BOLD|5216857|entityMap^0|0|0|0|0|0|0|0|1P|6|0|0|0|0|0|0|A|2|D|A|0^^$0|@$1|2|3|4|5|6|7|16|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|17|8|@]|9|@]|A|$]]|$1|C|3|D|5|E|7|18|8|@]|9|@]|A|$]]|$1|F|3|G|5|E|7|19|8|@]|9|@]|A|$]]|$1|H|3|I|5|E|7|1A|8|@]|9|@]|A|$]]|$1|J|3|K|5|E|7|1B|8|@]|9|@]|A|$]]|$1|L|3|M|5|6|7|1C|8|@]|9|@]|A|$]]|$1|N|3|O|5|6|7|1D|8|@$P|1E|Q|1F|R|S]]|9|@]|A|$]]|$1|T|3|U|5|6|7|1G|8|@]|9|@]|A|$]]|$1|V|3|-4|5|6|7|1H|8|@]|9|@]|A|$]]|$1|W|3|X|5|Y|7|1I|8|@]|9|@]|A|$]]|$1|Z|3|-4|5|6|7|1J|8|@]|9|@]|A|$]]|$1|10|3|-4|5|6|7|1K|8|@]|9|@]|A|$]]|$1|11|3|12|5|6|7|1L|8|@$P|1M|Q|1N|R|13]|$P|1O|Q|1P|R|13]]|9|@]|A|$]]|$1|14|3|-4|5|6|7|1Q|8|@]|9|@]|A|$]]]|15|$]]

A base class is a relative term. It only applies when considering one of its derived classes. Here are some terms that I consider opposites (and mostly orthogonal among themselves):

<ul>
<li>base class vs derived class; similarly super class vs sub class</li>
<li>abstract class vs concrete class</li>
<li>root class vs leaf class</li>
<li>sealed (also, final) class vs inheritable (non-sealed) class</li>
<li>nested class vs top-level class</li>
</ul>

Abstract and (normally) root classes are designed to be base classes. Sealed classes cannot be base classes, because they're non-inheritable. A root class is a class without a base class (in C# and Java, this class is <code>Object</code>). A leaf class has no subclass, so it's not a base class; but it's not necessarily sealed. Sealed classes, on the other hand, are always leaf classes.

So,

<blockquote>
 I am looking for the name of a class that has not been sub-classed, YET
</blockquote>

It seems that you're looking for a leaf class, but I don't consider it to be the opposite of a base class.

In object-oriented programming, a 'base class' is a class from which other classes have been derived (http://en.wikipedia.org/wiki/Base_class).

However, what is the opposite of a base class? In order words, what is a class that does NOT have any child classes called?

EDIT: I am looking for the name of a class that has not been sub-classed, YET, within an inheritance of tree of multiple parent classes, starting with a base class.

What is the opposite of a base class in OOP?

在面向对象编程中，“基类”是派生其他类的类()。然而，基类的对立面是什么呢？换句话说，没有任何子类的类是什么？编辑:我正在寻找一个没有子类的类的名称，但在多个父类的继承树中，从一个基类开始。
