hash_multiset : : upper_bound (STL/CLR)

Finds end of range that matches a specified key.

    iterator upper_bound(key_type key);

Paramètres

key
Key value to search for.

Notes

The member function determines the last element X in the controlled sequence that hashes to the same bucket as key and has equivalent ordering to key. If no such element exists, or if X is the last element in the controlled sequence, it returns hash_multiset : : fin (STL/CLR)(); otherwise it returns an iterator that designates the first element beyond X. You use it to locate the end of a sequence of elements currently in the controlled sequence that match a specified key.

Exemple

// cliext_hash_multiset_upper_bound.cpp 
// compile with: /clr 
#include <cliext/hash_set> 
 
typedef cliext::hash_multiset<wchar_t> Myhash_multiset; 
int main() 
    { 
    Myhash_multiset 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(); 
 
    System::Console::WriteLine("upper_bound(L'x')==end() = {0}", 
        c1.upper_bound(L'x') == c1.end()); 
 
    System::Console::WriteLine("*upper_bound(L'a') = {0}", 
        *c1.upper_bound(L'a')); 
    System::Console::WriteLine("*upper_bound(L'b') = {0}", 
        *c1.upper_bound(L'b')); 
    return (0); 
    }
