bind2nd (STL/CLR)

生成参数和 functor 的 binder2nd 。

template<typename Fun,
    typename Arg>
    binder2nd<Fun> bind2nd(Fun% functor,
        Arg right);

Template Parameters

• Arg
  参数类型。

• fun
  functor 的类型。

函数参数

• functor
  包装 functor。

• right
  包装的第二个参数。

备注

模板函数返回 binder2nd (STL/CLR)<Fun>(functor, right)。您将其用作一种简便方法包装两个参数 functor 及其第二个参数在调用其与第一个参数的一个参数 functor。

示例

// cliext_bind2nd.cpp 
// compile with: /clr 
#include <cliext/algorithm> 
#include <cliext/functional> 
#include <cliext/vector> 
 
typedef cliext::vector<int> Myvector; 
int main() 
    { 
    Myvector c1; 
    c1.push_back(4); 
    c1.push_back(3); 
    Myvector c3(2, 0); 
 
// display initial contents " 4 3" 
    for each (int elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// transform and display 
    cliext::minus<int> sub_op; 
    cliext::binder2nd<cliext::minus<int> > sub4(sub_op, 4); 
 
    cliext::transform(c1.begin(), c1.begin() + 2, c3.begin(), 
        sub4); 
    for each (int elem in c3) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// transform and display with function 
    cliext::transform(c1.begin(), c1.begin() + 2, c3.begin(), 
        bind2nd(sub_op, 4)); 
    for each (int elem in c3) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
    return (0); 
    }
