Function documentation

TRandom1()

TRandom1(UInt_t seed, Int_t lux = 3)

TRandom1(Int_t rowIndex, Int_t colIndex, Int_t lux)

virtual ~TRandom1()

Int_t GetLuxury() const

 Get the current seed (first element of the table)

{return fLuxury;}

UInt_t GetSeed() const

 Gets the current seed.

{ return UInt_t ( fFloatSeedTable[0] / fMantissaBit24 ) ; }

const UInt_t * GetTheSeeds() const

 Gets the current array of seeds.

{return fTheSeeds;}

void GetTableSeeds(UInt_t* seeds, Int_t index)

 Gets back seed values stored in the table, given the index.

Double_t Rndm()

void RndmArray(Int_t size, Float_t* vect)

void RndmArray(Int_t size, Double_t* vect)

void SetSeed2(UInt_t seed, Int_t lux = 3)

 Sets the state of the algorithm according to seed.

void SetSeeds(const UInt_t* seeds, Int_t lux = 3)

 Sets the state of the algorithm according to the zero terminated
 array of seeds. Only the first seed is used.

void SetSeed(ULong_t seed)
