Detailed Description

template<typename IntType = int, typename EngineType = std::mt19937>
class openvdb::v13_0::math::RandInt< IntType, EngineType >

Simple random integer generator.

Thread-safe as long as each thread has its own RandInt instance

Constructor & Destructor Documentation

RandInt ( const EngineType &  engine, IntType  imin, IntType  imax  )

inline

Initialize the generator.

Parameters

engine	random number generator
imin,imax	generate integers that are uniformly distributed over [imin, imax]

RandInt ( unsigned int  seed, IntType  imin, IntType  imax  )

inline

Initialize the generator.

Parameters

seed	seed value for the random number generator
imin,imax	generate integers that are uniformly distributed over [imin, imax]

Member Function Documentation

const EngineType& engine ( ) const

inline

Return a const reference to the random number generator.

IntType operator() ( )

inline

Return a randomly-generated integer in the current range.

IntType operator() ( IntType  imin, IntType  imax  )

inline

Return a randomly-generated integer in the new range [imin, imax], without changing the current range.

void setRange ( IntType  imin, IntType  imax  )

inline

Change the range over which integers are distributed to [imin, imax].

void setSeed ( unsigned int  seed )

inline

Set the seed value for the random number generator.
