Class UserCacheImpl

java.lang.Object

org.activiti.app.service.idm.UserCacheImpl

All Implemented Interfaces:

UserCache

@Service
public class UserCacheImpl
extends Object
implements UserCache

Cache containing User objects to prevent too much DB-traffic (users exist seperatly from the Activiti tables, they need to be fetched afterward one by one to join with those entities). TODO: This could probably be made more efficient with bulk getting. The Google cache impl allows this: override loadAll and use getAll() to fetch multiple entities.
