std::discard_block_engine(3) C++ Standard Libary std::discard_block_engine(3) NAME std::discard_block_engine - std::discard_block_engine Synopsis Defined in header <random> template< class Engine, (since C++11) std::size_t P, std::size_t R > class discard_block_engine; discard_block_engine is a pseudo-random number engine adaptor that discards a certain amount of data produced by the base engine. From each block of size P generated by the base engine, the adaptor keeps only R numbers, dis- carding the rest. Template parameters Engine - the type of the wrapped engine. P - the size of a block. Expected that \(\small{P>0}\)P > 0. R - the number of used numbers per block. Expected that \(\small{0<R\le P}\)0 < R P. Type requirements - Engine must meet the requirements of RandomNumberEngine. Member types Member type Definition result_type(C++11) Engine::result_type 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 re- turns 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 of the [static] (C++11) underlying engine.
