Public Member Functions  
BakerTransformedStream (RandomStream stream)  
Constructs a new baker transformed stream, using the random numbers from the base stream stream .  
void  resetStartStream () 
Reinitializes the stream to its initial state \(I_g\): \(C_g\) and \(B_g\) are set to \(I_g\).  
void  resetStartSubstream () 
Reinitializes the stream to the beginning of its current substream: \(C_g\) is set to \(B_g\).  
void  resetNextSubstream () 
Reinitializes the stream to the beginning of its next substream: \(N_g\) is computed, and \(C_g\) and \(B_g\) are set to \(N_g\).  
String  toString () 
Returns a string starting with "Baker transformation of " and finishing with the result of the call to the toString method of the generator.  
double  nextDouble () 
Returns the baker transformation of s.nextDouble() where s is the base stream.  
int  nextInt (int i, int j) 
Generates a random integer in \(\{i,...,j\}\) via nextDouble (in which the baker transformation is applied).  
void  nextArrayOfDouble (double[] u, int start, int n) 
Calls nextArrayOfDouble (u, start, n) for the base stream, then applies the baker transformation. More...  
void  nextArrayOfInt (int i, int j, int[] u, int start, int n) 
Fills up the array by calling nextInt (i, j) . More...  
This container class permits one to apply the baker’s transformation to the output of any RandomStream.
It transforms each \(u \in[0,1]\) into \(2u\) if \(u \le1/2\) and \(2(1u)\) if \(u > 1/2\). The nextDouble method will return the result of this transformation and the other next...
methods are affected accordingly. Any instance of this class contains a RandomStream called its base stream, used to generate its numbers and to which the transformation is applied. Any call to one of the next...
methods of this class will modify the state of the base stream.
The baker transformation is often applied when the RandomStream is actually an iterator over a point set used for quasiMonte Carlo integration (see the hups
package).
void nextArrayOfDouble  (  double []  u, 
int  start,  
int  n  
) 
Calls nextArrayOfDouble (u, start, n)
for the base stream, then applies the baker transformation.
u  the array in which the numbers will be stored 
start  the first index of u to be used 
n  the number of random numbers to put in u 
Implements RandomStream.
void nextArrayOfInt  (  int  i, 
int  j,  
int []  u,  
int  start,  
int  n  
) 
Fills up the array by calling nextInt (i, j)
.
i  the smallest possible integer to put in u 
j  the largest possible integer to put in u 
u  the array in which the numbers will be stored 
start  the first index of u to be used 
n  the number of random numbers to put in u 
Implements RandomStream.
