std::independent_bits_engine

科技促进发展：独立[医]位元[医]发动机

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

independent_bits_engine是一个随机数引擎适配器，它产生与包装引擎不同位数的随机数。

模板参数

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 type must be unsigned integral type.

类型要求

发动机必须符合RandomNumberEngine的要求。

-W必须大于零，且不大于STD：：数值[医]限值<UIntType>*数字。

成员类型

Member typeDefinition
result_typeUIntType

成员函数

(constructor)constructs the engine adaptor (public member function)
seedsets the state of the underlying engine (public member function)
basereturns the underlying engine (public member function)

世代

运算符%28%29提升基础引擎的状态，并返回生成值%28公共成员函数%29

丢弃将适配器%27s状态提升指定数量%28公共成员函数%29。

特征

敏静态获取输出范围%28中最小的可能值(始终为零%29)。%28公共静态成员功能%29

马克斯静态获取输出范围%28始终为2w-1%29中的最大可能值。%28公共静态成员功能%29

非会员职能

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