std::independent_bits_engine(3) | C++ Standard Libary | std::independent_bits_engine(3) |
NAME¶
std::independent_bits_engine - std::independent_bits_engine
Synopsis¶
Defined in header <random>
template<
class Engine,
std::size_t W, (since C++11)
class UIntType
> class independent_bits_engine;
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
the type of the generated random numbers. The effect is undefined
UIntType - 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 constructs the engine adaptor
(C++11) (public member function)
seed sets the state of the underlying engine
(C++11) (public member function)
base returns the underlying engine
(C++11) (public member function)
Generation¶
operator() advances the state of the underlying engine and
returns the
(C++11) generated value
(public member function)
discard advances the adaptor's state by a specified amount
(C++11) (public member function)
Characteristics¶
min gets the smallest possible value in the output range (always
zero).
[static] (C++11) (public static member function)
max gets the largest possible value in the output range (always 2w
[static] (C++11) - 1).
(public static member function)
Non-member functions¶
operator== compares the internal states of the adaptors and
operator!= underlying engines
(C++11) (function)
(C++11)(removed in C++20)
operator<< performs stream input and output on pseudo-random number
operator>> engine adaptor
(C++11) (function)
