- Constructor Detail
  - KISSRandom
```
public KISSRandom(int[] seed)
```
    Creates a new instance.
    
    Parameters:
    
    seed - Seed. If the length is larger than 4, only the first 4 elements will be used; if smaller, the remaining elements will be automatically set.
- Method Detail
  - getStateInternal
```
protected byte[] getStateInternal()
```
    Creates a snapshot of the RNG state.
    
    Overrides:
    
    getStateInternal in class IntProvider
    
    Returns:
    
    the internal state.
  - setStateInternal
```
protected void setStateInternal(byte[] s)
```
    Resets the RNG to the given state.
    
    Overrides:
    
    setStateInternal in class IntProvider
    
    Parameters:
    
    s - State (previously obtained by a call to BaseProvider.getStateInternal()).

    BaseProvider.checkStateSize(byte[],int)
  - next
```
public int next()
```
    Returns:
    
    the next random value.
