group
Return the group name of the algorithm used by the random number generator.- Returns:
- Group name of the algorithm.
-
stateBits
public int stateBits()Returns number of bits used to maintain state of seed.- Returns:
- number of bits used to maintain state of seed.
-
equidistribution
public int equidistribution()Returns the equidistribution of the algorithm.- Returns:
- the equidistribution of the algorithm.
-
period
Return the period of the algorithm used by the random number generator.- Returns:
- BigInteger period.

isHardware
public boolean isHardware()Return true if random generator is generated by hardware.- Returns:
- true if random generator is generated by hardware.
-
isArbitrarilyJumpable
public boolean isArbitrarilyJumpable()Return true if random generator is arbitrarily jumpable.- Returns:
- true if random generator is arbitrarily jumpable.
-
isJumpable
public boolean isJumpable()Return true if random generator is jumpable.- Returns:

-
create
Create an instance ofRandomGenerator
based on algorithm chosen.- Returns:
-
new in instance of
RandomGenerator
.
-
create
Create an instance ofRandomGenerator
based on algorithm chosen providing a starting long seed. If long seed is not supported by an algorithm then the no argument form of create is used.- Parameters:
-
seed
- long random seed value. - Returns:
-
new in instance of
RandomGenerator
.
-
create
Create an instance ofRandomGenerator
based on algorithm chosen providing a starting byte[] seed. If byte[] seed is not supported by an algorithm then the no argument form of create is used.- Parameters:
-
seed
- byte array random seed value. - Returns:
-
new in instance of
RandomGenerator
.
