hash_multimap::bucket_count (STL/CLR)
Compte le nombre de compartiments restant.
int bucket_count();
Notes
Les fonctions membres retourne le nombre actuel de compartiments restant.Vous l'utilisez pour déterminer la taille de la table de hachage.
Exemple
// cliext_hash_multimap_bucket_count.cpp
// compile with: /clr
#include <cliext/hash_map>
typedef cliext::hash_multimap<wchar_t, int> Myhash_multimap;
int main()
{
Myhash_multimap c1 = gcnew Myhash_multimap;
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();
// inspect current parameters
System::Console::WriteLine("bucket_count() = {0}", c1.bucket_count());
System::Console::WriteLine("load_factor() = {0}", c1.load_factor());
System::Console::WriteLine("max_load_factor() = {0}",
c1.max_load_factor());
System::Console::WriteLine();
// change max_load_factor and redisplay
c1.max_load_factor(0.25f);
System::Console::WriteLine("bucket_count() = {0}", c1.bucket_count());
System::Console::WriteLine("load_factor() = {0}", c1.load_factor());
System::Console::WriteLine("max_load_factor() = {0}",
c1.max_load_factor());
System::Console::WriteLine();
// rehash and redisplay
c1.rehash(100);
System::Console::WriteLine("bucket_count() = {0}", c1.bucket_count());
System::Console::WriteLine("load_factor() = {0}", c1.load_factor());
System::Console::WriteLine("max_load_factor() = {0}",
