我想使用初始化列表在构造函数中初始化私有std::ofstream
(例如,在main
中打开的文件)。我有以下代码:
class MyClass{
std::ofstream ofs;
public:
MyClass(const std::ofstream &ofs): ofs(ofs) { }
};
我得到以下编译错误:
error C2248: 'std::basic_ofstream<_Elem,_Traits>::basic_ofstream' : cannot access private member declared in class 'std::basic_ofstream<_Elem,_Traits>'
with
[
_Elem=char,
_Traits=std::char_traits<char>
]
c:\program files (x86)\microsoft visual studio 11.0\vc\include\fstream(1034) : see declaration of 'std::basic_ofstream<_Elem,_Traits>::basic_ofstream'
with
[
_Elem=char,
_Traits=std::char_traits<char>
]
这里发生了什么?
答案 0 :(得分:3)
basic_ofstream( const basic_ofstream& rhs) = delete; (5) (since C++11)
无法复制构造basic_ofstream
。
您可能正在使用pre-c ++ 11编译器,它在库中标记为private
。
