hash_set : : bucket_count (STL/CLR)

Compte le nombre de compartiments.

    int bucket_count();

Notes

Les méthodes retournent le nombre actuel de compartiments. Vous l'utilisez pour déterminer la taille de la table de hachage.

Exemple

// cliext_hash_set_bucket_count.cpp 
// compile with: /clr 
#include <cliext/hash_set> 
 
typedef cliext::hash_set<wchar_t> Myhash_set; 
int main() 
    { 
    Myhash_set c1; 
    c1.insert(L'a'); 
    c1.insert(L'b'); 
    c1.insert(L'c'); 
 
// display initial contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    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}", 
        c1.max_load_factor()); 
    return (0); 
    }
