抽象类

Maintenance can be a nightmare if we have concrete implementations for interfacing with some code and abstract classes and interfaces for other parts of the code (how would we then keep track of which is which and manage change?).

如果我们一部分代码用于实现具体界面，而另一部分代码是抽象类以及接口（那我们将如何跟踪哪一个是哪一个，以及管理变化），维护将会成为一场恶梦。

The abstract class named BaseSerializable has basic functionality to serialize and deserialize itself.

抽象类名为BaseSerializable已基本功能来序列化和反序列化本身。"/页"

NiGeometry is an abstract class because it does not contain any information about how vertices are organized into drawable objects.

NiGeometry 是一个抽象类因为他不包含任何顶点被组织到渲染对象的信息

Based on integrity, we discuss the change of the cluster order after induct adding information and abstract class.

基于完整性考虑，还讨论了加入附加信息的重要作用以及引入附加信息和抽象类后，测试次序的变化。

MetaRuby - MetaRuby contains miscellaneous libraries for a future Ruby-in-Ruby interpreter including Array/Hash/String as abstract classes, an undo queue, a statistical time-profiler, an event loop, a modular marshaller (\"ToSource\"), a specification for a modular+reflexive+homoiconic remote call system, a declarative type system, a schema for expressing Ruby source code as proper (non-special) Ruby objects, etc.

MetaRuby含有复杂库，用于未来Ruby-in-Ruby翻译器，包括作为抽象类的阵列、散列和字符串，一个撤销队列，一个统计时间配置文件，一个事件循环，一个模块整理器（\"ToSource\"），一个用于模块＋自反＋相同图标的远程访问系统的说明，一个说明型系统，一个用于把Ruby源代码表达成固有Ruby对象，等等。

I got a simple solution using abstract classes as it was not possible to access the user defined methods in the Parent object.

我得到一个简单的解决方案，使用抽象类，因为它无法访问用户定义的父对象的方法。

The first, the partial code that implements a function is contained in AbstractPaser, so it can be abstract only kind, cannot be interface.

第一，AbstractPaser中含有实现功能的部分代码，所以它只能是抽象类，不能是接口。

Although most objects are initialized by running an appropriate constructor, it is possible to initialize the data members of simple nonabstract classes directly.

尽管大多数对象可以通过运行适当的构造函数进行初始化，但是直接初始化简单的非抽象类的数据成员仍是可能的。

First, let's take a look at the visitable interface we declared it here as an abstract class, but we could have also made it as an interface

首先，让我们看一看在visitable界面的外观（我们在这里宣布，作为一个抽象类，但我们也可以作为它的接口

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
