## 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.
