set::key_comp (STL/CLR)

Copies the ordering delegate for two keys.

    key_compare^key_comp();

Remarks

The member function returns the ordering delegate used to order the controlled sequence. You use it to compare two keys.

Example

// cliext_set_key_comp.cpp 
// compile with: /clr 
#include <cliext/set> 
 
typedef cliext::set<wchar_t> Myset; 
int main() 
    { 
    Myset c1; 
    Myset::key_compare^ kcomp = c1.key_comp(); 
 
    System::Console::WriteLine("compare(L'a', L'a') = {0}", 
        kcomp(L'a', L'a')); 
    System::Console::WriteLine("compare(L'a', L'b') = {0}", 
        kcomp(L'a', L'b')); 
    System::Console::WriteLine("compare(L'b', L'a') = {0}", 
        kcomp(L'b', L'a')); 
    System::Console::WriteLine(); 
 
// test a different ordering rule 
    Myset c2 = cliext::greater<wchar_t>(); 
    kcomp = c2.key_comp(); 
 
    System::Console::WriteLine("compare(L'a', L'a') = {0}", 
        kcomp(L'a', L'a')); 
    System::Console::WriteLine("compare(L'a', L'b') = {0}", 
        kcomp(L'a', L'b')); 
    System::Console::WriteLine("compare(L'b', L'a') = {0}", 
        kcomp(L'b', L'a')); 
    return (0); 
    } 
 

compare(L'a', L'a') = False
compare(L'a', L'b') = True
compare(L'b', L'a') = False

compare(L'a', L'a') = False
compare(L'a', L'b') = False
compare(L'b', L'a') = True
