std:: independent_bits_engine

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

independent_bits_engine is a random number engine adaptor that produces random numbers with different number of bits than that of the wrapped engine.

Template parameters

Engine	-	the type of the wrapped engine
W	-	the number of bits the generated numbers should have
UIntType	-	the type of the generated random numbers. The effect is undefined unless the parameter is cv-unqualified and is one of unsigned short , unsigned int , unsigned long , or unsigned long long .
Type requirements
- Engine must meet the requirements of RandomNumberEngine .
- W must be greater than zero, and no greater than std:: numeric_limits < UIntType > :: digits .

Member types

Member type	Definition
result_type (C++11)	UIntType

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 (always zero). (public static member function)
max [static] (C++11)	gets the largest possible value in the output range (always 2 w - 1). (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)
