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 tosaveState
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 thestate
argument is incompatible with this instance.
