bind1st (STL/CLR)

會產生binder1st的引數，以及 functor。

template<typename Fun,
    typename Arg>
    binder1st<Fun> bind1st(Fun% functor,
        Arg left);

Template Parameters

• 引數
  引數型別。

• 娛樂特區
  Functor 型別。

函式參數

• functor
  若要自動換行 functor。

• left
  若要自動換行的第一個引數。

備註

樣板函式會傳回binder1st (STL/CLR)<Fun>(functor, left)。 您可以使用它以包裝兩個引數 functor，其第一個引數中包含第二個引數呼叫它的引數 functor 最方便的方法。

範例

// cliext_bind1st.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::binder1st<cliext::minus<int> > subfrom3(sub_op, 3); 
 
    cliext::transform(c1.begin(), c1.begin() + 2, c3.begin(), 
        subfrom3); 
    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(), 
        bind1st(sub_op, 3)); 
    for each (int elem in c3) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
    return (0); 
    }
