Method Detail
-
setSeed
void setSeed(byte[] seed)
Reseed this PRNG.- Parameters:
seed- The PRNG's new seed.
-
getNewSeedLength
int getNewSeedLength()
Returns the preferred length of a new byte-array seed. "Preferred" is implementation-defined when multiple seed lengths are supported, but should probably usually mean the longest one, since the longer the seed, the more random the output.- Returns:
- The desired length of a new byte-array seed.
-
preferSeedWithLong
boolean preferSeedWithLong()
Indicates whetherRandom.setSeed(long)is recommended oversetSeed(byte[])when the seed is already in the form of along.- Returns:
- true if
Random.setSeed(long)will tend to perform better thansetSeed(byte[]).
