- Method Detail
  - saveState
```
RandomProviderState saveState()
```
    Saves the state of a generator.
    
    Returns:
    
    the current state of this instance. It is a value that can subsequently be passed to the restore method.
    
    Throws:
    
    UnsupportedOperationException - if the underlying source of randomness does not support this functionality.
  - restoreState
```
void restoreState(RandomProviderState state)
```
    Restores the state of a generator.
    
    Parameters:
    
    state - State which this instance will be set to. This parameter would usually have been obtained by a call to saveState performed either on the same object as this one, or an object of the exact same class.
    
    Throws:
    
    UnsupportedOperationException - if the underlying source of randomness does not support this functionality.
    
    IllegalArgumentException - if it was detected that the state argument is incompatible with this instance.
