Description

`threefry_engine` public construct/copy/destruct

explicit threefry_engine(command_queue & queue);

Creates a new threefry_engine and seeds it with value.

threefry_engine(const threefry_engine< T > & other);

Creates a new threefry_engine object as a copy of other.

threefry_engine< T > & operator=(const threefry_engine< T > & other);

Copies other to *this.

```
~threefry_engine();
```
Destroys the threefry_engine object.

`threefry_engine` public member functions

template<typename OutputIterator> 
  void generate(OutputIterator first_ctr, OutputIterator last_ctr, 
                OutputIterator first_key, OutputIterator last_key, 
                command_queue & queue);

Generates Threefry random numbers using both the counter and key values, and then stores them to the range [first_ctr, last_ctr).

template<typename OutputIterator> 
  void generate(OutputIterator first_ctr, OutputIterator last_ctr, 
                command_queue & queue);
