C ++-Singleton类 [英] C++-Singleton class

问题描述

可以继承单例类.如是，那我们该怎么办呢?

Can a singleton class be inherited. if yes, then how can we do it?

*****我的意思是说，如果我们有一个使用单例设计模式的类，那么它可以被继承吗?*

*****I mean to say that if we have a class which uses singleton design pattern,then can it be inherited?*

推荐答案

singleton具有私有构造函数，因此无法进行继承.除了singleton之外，还有静态方法来实例化私有实例成员，并且由于您无法覆盖静态方法，因此从singleton继承是毫无意义的.

singleton has private constructor so inheritance is not possible. besides singleton has static methods to instantiate private instance member and since you can't override static methods it would be pointless to inherit from singleton.
