As mentioned above, the nested syntax is often mistaken for subclassing by users who are not already familiar with extensions.
正如上面所提到的，嵌套的语法通常被错误地认为有子类化的关系——尤其是对那些还不熟悉扩展的用户来说。
If the class can be overridden, its methods' behaviors can be overridden as well, so your safest bet is to disallow subclassing.
如果可以重写类的话，则可以重写它的方法的行为，因此您最安全的选择就是不允许将类子类化。
Either subclassing ThreadGroup or installing an implementation of this new interface allows you to change that default behavior.
细分ThreadGroup或安装该新接口的实现都允许您更改默认行为。
Subclassing potential. The longer a method is, the more difficult it will be to create effective subclasses that use the method.
拥有子类化潜力。函数越长，你就越难以创建一个子类使用这个函数。
Subclassing the class is typically not an option here, since the method needs to be available to instances of the base class itself.
在这种情况下，继承这个类通常是行不通的，因为所添加的方法需要在基类的实例中可用。
It turns out that subclassing is not only familiar but is probably the most flexible and straightforward way to map from model to view.
结果证明，子分类方法不但十分常用，而且还可能是从模型映射到视图最灵活也是最直接的方法。
Now we put our attention on how to subclass a window. Note that subclassing is not limited to controls, it can be used with any window.
现在我们把注意力放在如何子类化一个窗口上。注意，子类化并不是仅限制于控件，它能被用于任何窗口。

You've actually seen one instance of another class hierarchy that also serves as a good illustration of the idea of extension by subclassing.
你已经看到了另一个类层次的实例，它很好的阐明了子类化的概念。
Class abstractions are extended by subclassing and a flexible mixin-based composition mechanism as a clean replacement for multiple inheritance.
Class的抽象可由子类化和一种灵活的基于mixin的组合机制(它可作为多重继承的简单替代方案)来扩展。
I'll handle these differing requirements by using a base class for all parameter definitions, subclassing it for each specific type of parameter.
我处理这些不同需求的方法是，首先为所有形参定义使用一个基类，然后为每一种特定类型的形参细分类这个基类。
By its subclassing from this restriction, the RelevantResource class is a sort of virtual class that includes a set of all resources that meet the restriction.
通过从这一约束条件划分子类，RelevantResource类成为一种包含一个所有满足该约束条件资源集合的虚拟类。
Because it is not just for grids, you can use the flow layout to create interesting and flexible arrangements of your content both with and without subclassing.
因为流动布局不仅仅支持网络布局，不管你使用不使用子类化，你都可以使用流动布局创建流畅有趣的内容排布。
The only exception to this is when variables of the nested type need to be declared in rare scenarios such as subclassing or other advanced customization scenarios.
唯一的特例是需要声明嵌套类型的变量的情况，在生成子类或其他高级自定义等极少数情况下需要声明嵌套类型的变量。
Note that this is a working example of how to extend the functionality by aggregating objects — adding a BrowserExtension to a ReadOnlyPart — as opposed to subclassing.
注意，这是一个正在运行的示例，与子类化相对，它涉及如何通过聚合对象—将BrowserExtension添加到ReadOnlyPart—来扩展功能。
