hash_set::lower_bound (STL/CLR)

Finds beginning of range that matches a specified key.

    iterator lower_bound(key_type key);


Key value to search for.

The member function determines the first 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, it returns hash_set::end (STL/CLR)(); otherwise it returns an iterator that designates X. You use it to locate the beginning of a sequence of elements currently in the controlled sequence that match a specified key.
