# \_\_gnu\_pbds::sample\_range\_hashing(3)

A sample range-hashing functor.

## NAME

\_\_gnu\_pbds::sample\_range\_hashing - A sample range-hashing functor.

## SYNOPSIS

\#include \<sample\_range\_hashing.hpp\>

### Public Types

typedef std::size\_t **size\_type**\
 Size type.

### Public Member Functions

**sample\_range\_hashing** ()\
 Default constructor.  **sample\_range\_hashing** (const sample\_range\_hashing &other)\
 Copy constructor.  void **swap** (**sample\_range\_hashing** &other)\
 Swaps content.

### Protected Member Functions

void **notify\_resized** (**size\_type**)\
 Notifies the policy object that the container's size has changed to argument's size.  **size\_type** **operator()** (**size\_type**) const\
