    • TRANSIENT

      public static final DbEntityState TRANSIENT
      A transient object does not exist in the database and has been created by the current session. It will be INSERTed to the database and marked PERSISTENT with the next flush.

      public static final DbEntityState DELETED_TRANSIENT
      A transient object which does not exist in the database but has been created and deleted in the current session. It will not be flushed to the database and will be removed from the cache at the next flush.

    • DELETED_PERSISTENT
