Detailed Description

To generate the random numbers, the linear congruetial method is used. 2^32 is used as modulus. The overflow in the implementation is intended (and controlled, as UWORD32 is used as datatype which always is 32 bits wide).

Constructor & Destructor Documentation

PseudoRandomSource::PseudoRandomSource

(

UWORD32

s

)

[inline]

construct a PseudoRandomSource object

Parameters:

s

the seed

Member Function Documentation

UWORD32 PseudoRandomSource::getValue

(

UWORD32

n

)

get a pseudo-random value from {0,...,n-1}

Parameters:

n

the range of the random value to be returned

Returns:

a number >= 0 and <= n - 1

After calling getValue, the next getValue call will use the next state of the random number generator (analogous to the C rand() function)
