- All Implemented Interfaces:
IRandomStandalone,Serializable,Cloneable,Runnable
public class AsyncFortunaStandalone extends FortunaStandalone implements Runnable
fortuna instance that tries to avoid blocking if at all possible by using separate
filled buffer segments rather than one buffer (and blocking when that buffer's data
has been eaten)
Note that this class is not fully Thread safe!
The following methods must be synchronized externally, they are not
synced here or in super():
addRandomByte(), addRandomBytes(), nextByte(), nextBytes(), seed()
