A sample range-hashing functor.
This class serves to show the interface a range-hashing functor needs to support.
| 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). | 
| 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. | 
| 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. |
