◆ getRND16()
      
        
          | Uint16 OFRandom::getRND16 | ( |  | ) |  | 
      
 
return a random Uint16 value 
- Returns
- random unsigned 16-bit number 
 
 
◆ getRND32()
      
        
          | Uint32 OFRandom::getRND32 | ( |  | ) |  | 
      
 
return a random Uint32 value 
- Returns
- random unsigned 32-bit number 
 
 
◆ getRND64()
      
        
          | Uint64 OFRandom::getRND64 | ( |  | ) |  | 
      
 
return a random Uint64 value 
- Returns

◆ isaac()
generate next round of random numbers. 
Calling this method will cause the algorithm to generate a new set of random numbers in randrsl. 
 
 
◆ seed()
      
        
          | void OFRandom::seed | ( | Uint32 | sval | ) |  | 
      
 
Re-seed the PRNG with the given parameter. 
This method should only be used when a reproducible sequence of pseudo-random numbers is desired, e.g. in test routines.
