| Parameter | Description | Default Value | 
| class String | String type. | std::string | 
| typename String::value_type Min_E_Val | Minimal element. | SCHAR_MIN | 
| typename String::value_type Max_E_Val | Maximal element. | SCHAR_MAX | 
| bool Reverse | Indicates whether reverse iteration should be used. | false | 
| class Allocator | Allocator type. | std::allocator<char> | 
| Type | Definition | Description | 
| size_type | typename Allocator::size_type | Size type. | 
| Type | Definition | Description | 
| key_type | String | Key type. | 
| const_key_reference | typename Allocator::template rebind< key_type>::other::const_reference | Const key reference type. | 
| Type | Definition | Description | 
| reverse | Reverse | Reverse iteration indicator. | 
| const_iterator | 
typename __gnu_pbds::detail::__conditional_type<
    Reverse,
    typename String::const_reverse_iterator,
    typename String::const_iterator>::__type
 | Element const iterator type. | 
| e_type | typename std::iterator_traits<const_iterator>::value_type | Element type. | 
| min_e_val | Min_E_Val | Minimal element. |

| max_size | max_e_val - min_e_val + 1 | Number of distinct elements. | 
| Method | Description | 
| inline static const_iterator begin (const_key_reference r_key) | Returns a const_iterator to the first element of r_key. | 
| inline static const_iterator end (const_key_reference r_key) | Returns a const_iterator to the after-last element of r_key. | 
| inline static size_type e_pos (e_type e) | Maps an eelement to a position. |
