hash_map::key_comp (STL/CLR)
將複製兩個索引鍵的順序的委派。
key_compare^key_comp();
備註
成員函式會傳回用於排序受控制的序列的順序委派。 您會用它來比較兩個索引鍵。
範例
// cliext_hash_map_key_comp.cpp
// compile with: /clr
#include <cliext/hash_map>
typedef cliext::hash_map<wchar_t, int> Myhash_map;
int main()
{
Myhash_map c1;
Myhash_map::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_map 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);
}
