Detailed Description

Uniform Random Generator.

<>

Constructor & Destructor Documentation

◆ RandGen()

Stats::RandGen::RandGen ( )

Member Function Documentation

◆ get()

virtual double Stats::RandGen::get ( ) const

virtual

Uniform [0-1].

Implements Stats::RandomGenerator.

◆ getIndex() [1/2]

int Stats::RandGen::getIndex ( int sz ) const

random index in the range [0,sz>

◆ getIndex() [2/2]

od_int64 Stats::RandGen::getIndex ( od_int64 sz ) const

random index in the range [0,sz>

◆ getIndexFast() [1/2]

int Stats::RandGen::getIndexFast	(	int	sz,
		int	seed
	)		const

getIndex using a very simple random generator

◆ getIndexFast() [2/2]

od_int64 Stats::RandGen::getIndexFast	(	od_int64	sz,
		od_int64	seed
	)		const

getIndex using a very simple random generator

◆ getInt() [1/2]

int Stats::RandGen::getInt ( ) const

Uniform int.

◆ getInt() [2/2]

int Stats::RandGen::getInt	(	int	min,
		int	max
	)		const

random int in the range [min,max]>

◆ subselect() [1/3]

template<class ODSET >

void Stats::RandGen::subselect	(	ODSET &	ods,
		od_int64	targetsz
	)		const

inline

◆ subselect() [2/3]

template<class T >

void Stats::RandGen::subselect	(	T &	,
		od_int64	targetsz
	)		const

Does not preserve order The removed items will really be erased

◆ subselect() [3/3]

template<class T , class SzTp >

void Stats::RandGen::subselect	(	T *	arr,
		SzTp	sz,
		SzTp	targetsz
	)		const
