Enum FallbackPolicy

java.lang.Object
  java.lang.Enum<FallbackPolicy>
      org.random.rjgodoy.trng.FallbackPolicy

All Implemented Interfaces:

Serializable, Comparable<FallbackPolicy>

public enum FallbackPolicy
extends Enum<FallbackPolicy>

Values for the org.random.rjgodoy.trng.fallback property.

When the quota is exhausted, the generator may fallback to use a local PRNG, or it may wait (several minutes) until the quota is positive again.

Enum Constant Summary

PRNG
The RNG will return true random numbers from the remote source if the quota is positive, and will use a local PRNG if the quota is negative.

TRNG
The RNG will return true random numbers from the remote source if the quota is positive, and will sleep if the quota is negative.

Method Summary

static FallbackPolicy	valueOf(String name) Returns the enum constant of this type with the specified name.

Enum Constant Detail

TRNG

public static final FallbackPolicy TRNG

The RNG will return true random numbers from the remote source if the quota is positive, and will sleep if the quota is negative.

PRNG

public static final FallbackPolicy PRNG

The RNG will return true random numbers from the remote source if the quota is positive, and will use a local PRNG if the quota is negative.

The PRNG must be seed by the application code, by calling SecureRandom.setSeed(byte[]) on the instantiated SecureRandom object.

Method Detail

values

public static FallbackPolicy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (FallbackPolicy c : FallbackPolicy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static FallbackPolicy valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
