Class BaseUserCache

java.lang.Object

org.flowable.ui.common.service.idm.cache.BaseUserCache

All Implemented Interfaces:

UserCache

Direct Known Subclasses:

RemoteIdmUserCache

public abstract class BaseUserCache
extends Object
implements UserCache

Cache containing User objects to prevent too much DB-traffic (users exist separately from the Flowable 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.
