hash_multimap::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_hash_multimap_key_comp.cpp
// compile with: /clr
#include <cliext/hash_map>
typedef cliext::hash_multimap<wchar_t, int> Myhash_multimap;
int main()
{
Myhash_multimap c1;
Myhash_multimap::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
Myhash_multimap 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') = True
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
