private constructors的意思|示意

Using private constructors for factory methods?

使用私有构造函数的工厂方法？

Implement standard OOP features like private constructors, abstract methods and classes.

实现标准的面向对象功能，比如：私有构造函数、抽象方法和抽象类等。

That is, private constructors, methods, fields, and properties can be accessed and invoked using Reflection whenever the code is fully trusted.

也就是说，只要程序码完全受到信任，就可以使用反映来存取和叫用私用建构函式、方法、栏位和属性。

If a class has one or more private constructors and no public constructors, other classes (except nested classes) cannot create instances of this class.

如果类具有一个或多个私有构造函数而没有公共构造函数，则其他类(除嵌套类外)无法创建该类的实例。

You should not use your instance constructors, some special private function, or any other idiom to initialize static variables.

不应该使用实例构造函数、一些特殊的私有方法、任何其它习惯来初始化静态变量。

One possible implementation is to use this method as a hook into your own private class initialization routines that are not already enabled by constructors.

一个可能的实现是，将此方法用作构造函数尚未启用的您自己的私有类初始化例程的挂钩。
