This means that all the private members of the class element are dumped first, followed by protected and public, respectively.
这意味着类元素的所有的私有成员都将被首先转储，然后依次是被保护的成员和公共的成员。
One interesting side effect of this approach is that it allows us to access private and protected members of a class via a closure, which can be handy for unit testing classes.
这种方法的一个有趣的副作用是允许通过闭包访问类的私有成员和受保护成员，这有利于对类执行单元测试。
Marking the base class as "private" allowed the derived class to inherit from it without actually becoming one of them.
将基类标记为 “私有”允许派生类从该基类继承而来，而无需实际成为 一个基类。

There is a convention in Objective-C to provide private methods on a class by defining a category within the implementation file; this could be a relatively simple addition by using chained templates.
在Objective - C中有一个惯例通过在实现文件中定义一个类别为一个类提供了私有的方法；通过使用链式模版这将是相关简单的附加物。
The reality is that the main() method simply executes a private method, go(), on an instantiated AtomToRdf class.
实际情况是main()方法只是在一个实例化的AtomToRdf 类上执行了一个私有方法go()。
Not only are the variables private but they are private to the particular instance of the Converter class.
这些变量不仅是私有的，而且只属于converter类的特定实例。
As the name suggests, the convert local variable to field refactoring takes a local variable and converts it to a private field of the class.
正如其名称所示，这个ConvertLocalVariabletoField重构能够获取一个本地变量并将这个变量转换为此类的一个私有字段。
If a class contains only static members, remember to mark the class as static or seal the class (NotInheritable) and give the class a private constructor to avoid instance creation.
如果类只包含静态成员，则要记得将该类标记为静态，或者密封该类(NotInheritable)，并且还要为该类提供一个私有构造函数，以避免实例创建。
Properties that are public can be written to and read from outside the class. Properties that are private can only be seen within the object or class context.
声明为public的属性可以在类外部写入和读取，声明为private的属性只在对象或类上下文中可见。
One of the most useful of these is the PrivateAccessor class, which makes testing private methods a snap regardless of your testing framework of choice.
其中最有用的一个就是privateaccessor类，它把对private方法的测试变成小菜一碟，无论选择的测试框架是什么。
Often this means the proxy will need to be an inner class of Person to have access to private fields.
这通常意味着代理需要是Person的一个内部类，以便能访问private字段。
