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
and delivers a randomly selected number from that table when requested, replacing it with a number generated by the base engine.
The following typedef defines the random number engine with one commonly used parameter set:

Member functions
(C++11) |
constructs the engine adaptor (public member function) |
(C++11) |
sets the state of the underlying engine (public member function) |
(C++11) |
returns the underlying engine (public member function) |
Generation | |
(C++11) |
advances the state of the underlying engine and returns the generated value (public member function) |
(C++11) |
advances the adaptor's state by a specified amount (public member function) |
Characteristics | |
[static] (C++11) |
gets the smallest possible value in the output range of the underlying engine. (public static member function) |
[static] (C++11) |
gets the largest possible value in the output range of the underlying engine. (public static member function) |
Non-member functions
(C++11)(C++11)(removed in C++20) |
compares the internal states of the adaptors and underlying engines (function) |
(C++11) |
performs stream input and output on pseudo-random number engine adaptor (function) |
Member objects
constexpr size_t table_size [static] |
the size of the internal table, K (public static member constant) |
