小编CK1*_*CK1的帖子

我想要移植一些代码,它们对C++ 11使用了boost :: unwrap_reference.代码调用很多成员函数,比如

template< typename T, typename Y>
void initialize( T _t, Y y)
{

    typename boost::unwrap_reference< T >::type & t = _t;

    t.doSomethingNastyWithY( y );
}   

// The function is called like this
struct DoSomething
{
     template<typename Y>
     void doSomethingNastyWithY(Y y)
     {
         // do stuff
     }
};

struct Object {};

DoSomething s;
Object obj;

int main()
{
    initialize( s, obj ); // Take a copy of DoSomething
    initialize( boost::ref(s), obj ); // Uses DoSomething as reference
}

我在STL中找不到与boost …
