Constructor Detail

ThreadSafe

public ThreadSafe(XOR32ShiftRandom.Shift shift,
                  XOR32ShiftRandom.Param param,
                  byte[] seed)

Create a new PRNG instance with the given shift, parameter and seed.

Parameters:

shift - the shift strategy of the PRNG

param - the parameter of the PRNG.

seed - the seed of the PRNG.

Throws:

NullPointerException - if the given shift, param or seed is null.

IllegalArgumentException - if the given seed is shorter than XOR32ShiftRandom.SEED_BYTES

ThreadSafe

public ThreadSafe(XOR32ShiftRandom.Param param,
                  byte[] seed)

Create a new PRNG instance with the given parameter and seed.

Parameters:

param - the parameter of the PRNG.

seed - the seed of the PRNG.

Throws:

NullPointerException - if the given param or seed is null.

IllegalArgumentException - if the given seed is shorter than XOR32ShiftRandom.SEED_BYTES

ThreadSafe

public ThreadSafe(XOR32ShiftRandom.Param param,
                  long seed)

Create a new PRNG instance with the given parameter and seed.

Parameters:

seed - the seed of the PRNG.

param - the parameter of the PRNG.

Throws:

NullPointerException - if the given param is null.

ThreadSafe

public ThreadSafe(XOR32ShiftRandom.Param param)

Create a new PRNG instance with the given parameter and a safe seed

Parameters:

Method Detail

setSeed

public void setSeed(byte[] seed)

Description copied from class: XOR32ShiftRandom

Set the seed value of the PRNG.

Overrides:

setSeed in class XOR32ShiftRandom

Parameters:

seed - the seed value.

setSeed

public void setSeed(long seed)

Overrides:
