hash_multiset::key_compare (STL/CLR)
The ordering delegate for two keys.
Microsoft::VisualC::StlClr::BinaryDelegate<GKey, GKey, bool>
key_compare;
Remarks
The type is a synonym for the delegate that determines the ordering of its key arguments.
Example
// cliext_hash_multiset_key_compare.cpp
// compile with: /clr
#include <cliext/hash_set>
typedef cliext::hash_multiset<wchar_t> Myhash_multiset;
int main()
{
Myhash_multiset c1;
Myhash_multiset::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_multiset 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
