Detailed Description¶
template<class _UniformRandomNumberGenerator, int __p, int __r>class std::discard_block< _UniformRandomNumberGenerator, __p, __r >¶
Produces random numbers from some base engine by discarding blocks of data. 0 <= __r <= __p Definition at line 1078 of file tr1_impl/random.Member Typedef Documentation¶
template<class _UniformRandomNumberGenerator, int __p, int __r> typedef _UniformRandomNumberGenerator std::discard_block< _UniformRandomNumberGenerator, __p, __r >:: base_type¶
The type of the underlying generator engine. Definition at line 1085 of file tr1_impl/random.template<class _UniformRandomNumberGenerator, int __p, int __r> typedef base_type::result_type std::discard_block< _UniformRandomNumberGenerator, __p, __r >:: result_type¶
The type of the generated random value. Definition at line 1087 of file tr1_impl/random.Constructor & Destructor Documentation¶
template<class _UniformRandomNumberGenerator, int __p, int __r> std::discard_block< _UniformRandomNumberGenerator, __p, __r >:: discard_block () [inline]¶
Constructs a default discard_block engine. The underlying engine is default constructed as well. Definition at line 1098 of file tr1_impl/random.template<class _UniformRandomNumberGenerator, int __p, int __r> std::discard_block< _UniformRandomNumberGenerator, __p, __r >:: discard_block (const base_type &__rng) [inline], [explicit]¶
Copy constructs a discard_block engine. Copies an existing base class random number generator. Parameters:rng An existing (base class) engine
object.
template<class _UniformRandomNumberGenerator, int __p, int __r> std::discard_block< _UniformRandomNumberGenerator, __p, __r >:: discard_block (unsigned long__s) [inline], [explicit]¶
Seed constructs a discard_block engine. Constructs the underlying generator engine seeded with __s. Parameters:__s A seed value for the base class
engine.
template<class _UniformRandomNumberGenerator, int __p, int __r> template<class _Gen > std::discard_block< _UniformRandomNumberGenerator, __p, __r >:: discard_block (_Gen &__g) [inline]¶
Generator construct a discard_block engine. Parameters:__g A seed generator function.
