3. Protected Methods:
   1. Notification methods.
   2. Operators.

## Constructors, destructor, and related.

Method | Description
      sample_range_hashing
      ()
| Default constructor. Must be default constructible.
      sample_range_hashing
      (const sample_range_hashing &r_other)
| Copy constructor. Must be copy constructible.
    inline void
      swap
      (sample_range_hashing &r_other)
| Swaps content. Must be swappable (if there is such a word).

## Notification methods.

Method | Description
    void
      notify_resized
      (size_type size)
| Notifies the policy object that the container's size has changed to `size`. `size_type` is the size type on which the functor operates.

## Operators.

Method | Description
    *  comment = "@@sample_range_hashing_size_type_comment">
    **/
    inline size_type
      operator()
      (size_type hash) const
| Transforms the hash value `hash` into a ranged-hash value.
