Class RandomSeedRepo

java.lang.Object
  org.powertac.common.repo.RandomSeedRepo

All Implemented Interfaces:

org.powertac.common.repo.DomainRepo

@Repository
public class RandomSeedRepo
extends Object
implements org.powertac.common.repo.DomainRepo

Repository for RandomSeed instances. RandomSeeds are acquired by calls to getRandomSeed(). These will be newly-constructed only if an existing RandomSeed with the same classname, id, and purpose has not already been created. Seeds may be created by loading a logfile from an existing game, in which case the same random sequences will be repeated in the current game. Otherwise they are created with random starting points when requested.
