std::shuffle_order_engine

Defined in header <random>
template < class Engine,     std::size_t K > class shuffle_order_engine;		(since C++11)

shuffle_order_engine is a random number engine adaptor that shuffles the random numbers generated by the base engine. It maintains a table of size K

The following typedef defines the random number engine with one commonly used parameter set:

Defined in header <random>
Type	Definition
knuth_b (C++11)	std:: shuffle_order_engine < std::minstd_rand0, 256 >

Template parameters

Engine	-	the type of the wrapped engine
K	-	the size of the internal table. Must be greater than 0.
Type requirements
- Engine must meet the requirements of RandomNumberEngine

Member types

Member type	Definition
result_type (C++11)	Engine::result_type

Member functions

(constructor) (C++11)	constructs the engine adaptor (public member function)
seed (C++11)	sets the state of the underlying engine (public member function)
base (C++11)	returns the underlying engine (public member function)
Generation
operator() (C++11)	advances the state of the underlying engine and returns the generated value (public member function)
discard (C++11)	advances the adaptor's state by a specified amount (public member function)
Characteristics
min [static] (C++11)	gets the smallest possible value in the output range of the underlying engine. (public static member function)
max [static] (C++11)	gets the largest possible value in the output range of the underlying engine. (public static member function)

Non-member functions

operator==operator!= (C++11)(C++11)(removed in C++20)	compares the internal states of the adaptors and underlying engines (function)
operator<<operator>> (C++11)	performs stream input and output on pseudo-random number engine adaptor (function)

Member objects

constexpr size_t table_size [static] (C++11)

the size of the internal table, K (public static member constant)
