addSeedMaterial
public void addSeedMaterial(byte[] seed)
Add more seed material to the generator.
seed
- a byte array to be mixed into the generator's state.
addSeedMaterial
public void addSeedMaterial(long seed)
Add more seed material to the generator.
seed
- a long value to be mixed into the generator's state.
nextBytes
public void nextBytes(byte[] bytes)
Fill bytes with random values.
bytes
- byte array to be filled.
nextBytes
public void nextBytes(byte[] bytes,
int start,
int len)
Fill part of bytes with random values.
bytes
- byte array to be filled.start
- index to start filling at.len
- length of segment to fill.
