Method Detail

addSeedMaterial

public void addSeedMaterial(byte[] seed)

Add more seed material to the generator.

Parameters:

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.

Parameters:

seed - a long value to be mixed into the generator's state.

nextBytes

public void nextBytes(byte[] bytes)

Fill bytes with random values.

Parameters:

bytes - byte array to be filled.

nextBytes

public void nextBytes(byte[] bytes,
                      int start,
                      int len)
