RandomSeed (Power TAC server modules 1.8.0-SNAPSHOT API)

java.lang.Object
- java.util.Random
- - org.powertac.common.RandomSeed

All Implemented Interfaces:

Serializable
```
public class RandomSeed
extends Random
```
RandomSeed is used to store generated random seed in the database in order to be able to "replay" PowerTAC competitions later on with exactly the same random seed settings as originally used.
Note that server code is not intended to create instances of RandomSeed directly. Instead, please request seeds through RandomSeedRepo.getRandomSeed(). This way, your code will work the same whether using new seeds or replaying a previous simulation.

State log entry format:
requesterClass::requesterId::purpose::value
