collection_adapter::key_type (STL/CLR)
The type of a dictionary key.
typedef Key key_type;
Remarks
The type is a synonym for the template parameter Key, in a specialization for IDictionary or IDictionary<Value>; otherwise it is not defined.
Example
// cliext_collection_adapter_key_type.cpp
// compile with: /clr
#include <cliext/adapter>
#include <cliext/map>
typedef cliext::map<wchar_t, int> Mymap;
typedef cliext::collection_adapter<
System::Collections::Generic::IDictionary<wchar_t, int>> Mycoll;
typedef System::Collections::Generic::KeyValuePair<wchar_t,int> Mypair;
int main()
{
Mymap d1;
d1.insert(Mymap::make_value(L'a', 1));
d1.insert(Mymap::make_value(L'b', 2));
d1.insert(Mymap::make_value(L'c', 3));
Mycoll c1(%d1);
// display contents " [a 1] [b 2] [c 3]"
for each (Mypair elem in c1)
{
Mycoll::key_type key = elem.Key;
Mycoll::mapped_type value = elem.Value;
System::Console::Write(" [{0} {1}]", key, value);
}
System::Console::WriteLine();
return (0);
}
[a 1] [b 2] [c 3]
