如何防止基类中的函数从子类重载 [英] How to prevent a function in base class being overloaded from child class
问题描述
问题与主题一样。
例如：
class BaseClass {
public：
void func（）{做某事; } //我不希望这个函数在其继承的类中重载
};
class ChildClass： BaseClass {
public：
void func（）{do otherthing; } //这应该被禁止当
编译
}
Question is as in subject.
For example:
class BaseClass {
public:
void func() { do something; } // I don''t want this function being
overloaded in its inherited class
};
class ChildClass : BaseClass {
public:
void func() { do otherthing; } // this should be inhibited when
compiling
}

对不起，错字，应该是：禁止
编译
}

sorry, typo, should be: prohibited
compiling
}

''ChildClass :: func''不会重载''BaseClass： ：FUNC'。来自基类的''func''
名称是派生类''成员的_hidden_。
也许当你了解事情如何运作时，你不需要你要求的预防
。您认为您将通过阻止您所谓的重载来解决什么特别的问题？

The ''ChildClass::func'' does not overload ''BaseClass::func''. The ''func''
name from the base class is _hidden_ by the derived class'' member.
Perhaps when you learn how things work, you won''t need the "prevention"
you ask about. What particular problem do you think you''re going to
solve by preventing what you call "overloading"?

The problem of a derived class designer trying to solve problems in a
problem domain that the base class designer knows little or nothing
about, using techniques that the base class designer didn''t think of.
