      Pseudo-random number generation

      (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 sizeK 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:

      [edit]Template parameters

      Engine - the type of the wrapped engine
      K - the size of the internal table. Must be greater than0.
      Type requirements
      -
      Engine must meet the requirements ofRandomNumberEngine.

      (public member function)[edit]
      (C++11)
      sets the state of the underlying engine
      (public member function)[edit]
      (C++11)

      Characteristics
      [static](C++11)
      gets the smallest possible value in the output range of the underlying engine.
      (public static member function)[edit]
      [static](C++11)
      gets the largest possible value in the output range of the underlying engine.
      (public static member function)[edit]

      [edit]Non-member functions

      (C++11)(C++11)(removed in C++20)
