map::key_type (STL/CLR)

The type of an ordering key.

    typedef Key key_type;

Remarks

The type is a synonym for the template parameter Key.

Example

// cliext_map_key_type.cpp 
// compile with: /clr 
#include <cliext/map> 
 
typedef cliext::map<wchar_t, int> Mymap; 
int main() 
    { 
    Mymap c1; 
    c1.insert(Mymap::make_value(L'a', 1)); 
    c1.insert(Mymap::make_value(L'b', 2)); 
    c1.insert(Mymap::make_value(L'c', 3)); 
 
// display contents " [a 1] [b 2] [c 3]" using key_type 
    for (Mymap::iterator it = c1.begin(); it != c1.end(); ++it) 
        {   // store element in key_type object 
        Mymap::key_type val = it->first; 
 
        System::Console::Write(" {0}", val); 
        } 
    System::Console::WriteLine(); 
    return (0); 
    }
