public
construct/copy/destructexplicit 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 functionstemplate<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).
