hash_multimap : : échange (STL/CLR)
Échange le contenu de deux conteneurs.
void swap(hash_multimap<Key, Mapped>% right);
Paramètres
- right
Conteneur avec lequel échanger le contenu.
Notes
La méthode permute les séquences contrôlées entre this et right. Elle le fait en un temps constant et ne lève pas d'exception. Vous l'utilisez comme méthode rapide d'échange du contenu de deux conteneurs.
Exemple
// cliext_hash_multimap_swap.cpp
// compile with: /clr
#include <cliext/hash_map>
typedef cliext::hash_multimap<wchar_t, int> Myhash_multimap;
int main()
{
Myhash_multimap c1;
c1.insert(Myhash_multimap::make_value(L'a', 1));
c1.insert(Myhash_multimap::make_value(L'b', 2));
c1.insert(Myhash_multimap::make_value(L'c', 3));
// display contents " [a 1] [b 2] [c 3]"
for each (Myhash_multimap::value_type elem in c1)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
// construct another container with repetition of values
Myhash_multimap c2;
c2.insert(Myhash_multimap::make_value(L'd', 4));
c2.insert(Myhash_multimap::make_value(L'e', 5));
c2.insert(Myhash_multimap::make_value(L'f', 6));
for each (Myhash_multimap::value_type elem in c2)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
// swap and redisplay
c1.swap(c2);
for each (Myhash_multimap::value_type elem in c1)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
for each (Myhash_multimap::value_type elem in c2)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
return (0);
}
