Class RandomSeedGenerator
- All Implemented Interfaces:
Serializable
,Cloneable
This class has entirelly deterministic behaviour: Constructing two instances with the same parameters at any two distinct points in time will produce identical seed sequences. However, it does not (at all) generate uniformly distributed numbers. Do not use it as a uniformly distributed random number generator!
Each generated sequence of seeds has a period of 109 numbers.
Internally uses RandomSeedTable

RandomSeedGenerator
public RandomSeedGenerator(int row, int column) Constructs and returns a new seed generator; you normally won't need to use this method.The position [row,column] indicates the iteration starting point within a (virtual) seed matrix. The seed matrix is a n*m matrix with 1 + Integer.MAX_VALUE (virtual) rows and RandomSeedTable.COLUMNS columns. Successive calls to method nextSeed() will cycle over the given column, in ascending order: nextSeed() returns the seed s[row,column], s[row+1,column], ... s[Integer.MAX_VALUE,column], s[0,column], s[1,column], ...
- Parameters:
row
- should be in [0,Integer.MAX_VALUE].column
- should be in [0,RandomSeedTable.COLUMNS - 1].
