discard_block::base_type
O tipo do mecanismo aleatório.
typedef Engine base_type;
Comentários
O tipo base é um sinónimo para o tipo de objeto subjacente do mecanismo.
Exemplo
// std_tr1__random__discard_block_base_type.cpp
// compile with: /EHsc
#include <random>
#include <iostream>
typedef std::mt19937 Myeng;
typedef std::discard_block<Myeng, 2, 1> Myceng;
int main()
{
Myeng eng;
Myceng ceng;
const Myceng::base_type& base = ceng.base(); // get base engine
Myceng::result_type compval = ceng();
compval = compval; // to quiet "unused" warnings
base.min();
std::cout << "P == " << Myceng::block_size << std::endl;
std::cout << "R == " << Myceng::used_block << std::endl;
std::cout << "min == " << ceng.min() << std::endl;
std::cout << "max == " << ceng.max() << std::endl;
ceng.seed(); // reseed base engine
std::cout << "a random value == " << ceng() << std::endl;
std::cout << "a random value == " << ceng() << std::endl;
std::cout << "a random value == " << ceng() << std::endl;
Myceng ceng2(eng); // construct with generator
ceng2.seed(eng); // seed with generator
return (0);
