拷贝构造函数 meaning in Chinese
copy constructor
Examples
- If constructors , copy constructors , assignment and other things are added then the collection class becomes slower
如果增加了构造函数，拷贝构造函数，赋值和其它功能，这样集合类的速度会变慢。 - Because a template constructor is never a copy constructor , the presence of such a template does not suppress the implicit declaration of a copy constructor
由于模板构造函数终究不是拷贝构造函数，因此这种模板的出现并不会隐藏原来隐含的拷贝构造函数之声明。 - Although this may at first seem like only an efficiency concern ( and you normally don ' t want to concern yourself with efficiency tuning while you ' re designing and assembling your program ) , there ' s more at stake : as you ' ll see in the remainder of the chapter , a copy - constructor is required to pass an object by value , and this isn ' t always available
尽管初看起来，仅仅是一个与效率相关的难题（并且你在设计和装配程序时，一般不会想到通过调整效率来关心一下自己的程序） ，这更像是在赌博：本章余下的内容中你将会看到，通过传值方式需要给对象传递一个拷贝构造函数，但并不老是行得通。
