Public Types | |
| typedef double | result_type |
| STL required functor result type. | |
Public Member Functions | |
| double | operator() () const |
| UniformRandomFunctor (double lower, double upper, Engine &generator=Engine::global()) | |
| UniformRandomFunctor (Engine const &generator=Engine::global()) | |
This functor encapsulates the function uniform() of the given random number Engine (usually RandomTT800 or RandomMT19937) in an STL-compatible interface.
Traits defined:
FunctorTraits<UniformIntRandomFunctor<Engine> >isInitializer is true (VigraTrueType).
| UniformRandomFunctor | ( | Engine const & | generator = Engine::global() |
) |
Create functor for uniform random double-precision numbers in the range [0.0, 1.0] using the given engine.
That is, the generated numbers satisfy 0.0 <= i <= 1.0.
| UniformRandomFunctor | ( | double | lower, | |
| double | upper, | |||
| Engine & | generator = Engine::global() | |||
| ) |
Create functor for uniform random double-precision numbers in the range [lower, upper] using the given engine.
That is, the generated numbers satisfy lower <= i <= upper.
| double operator() | ( | ) | const |
Return a random number as specified in the constructor.
