Constructor Detail

NESRandom

public NESRandom()

Creates a new pseudorandom number generator. The seed is initialized to the current time, as if by setSeed(System.currentTimeMillis());.

System.currentTimeMillis()

NESRandom

public NESRandom(long seed)

Creates a new pseudorandom number generator, starting with the specified seed, using setSeed(seed);.

Parameters:

seed - the initial seed

Method Detail

setSeed

public void setSeed(long seed)

Sets the seed for this pseudorandom number generator. As described above, two instances of the same random class, starting with the same seed, produce the same results, if the same methods are called.

Overrides:

setSeed in class java.util.Random

Parameters:

seed - the new seed

getSeed

public long getSeed()

Returns the current state of the seed, can be used to clone the object

Returns:

the current seed

clone

public NESRandom clone()

Creates a clone of this object based on its current seed.

Overrides:

clone in class java.lang.Object

Returns:

A clone of this random generator object.
