hash_set::upper_bound (STL/CLR)

Finds end of range that matches a specified key.

    iterator upper_bound(key_type key);


Key value to search for.

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_set::end (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.
