| changeCandidates | | public synchronized void changeCandidates(List metas, Long endSerial, Long txSerial)(Code) | | This method registers "potential" change serials for a given id. The
change becomes final only when the transaction's commit ends.
|
| endTransaction | | public synchronized void endTransaction(Long txSerial)(Code) | | Ends a transaction, which means it finalizes the entries associated
with the given transaction.
|
| isCurrent | | public synchronized SessionInfo isCurrent(LockMetaData meta)(Code) | | This is the query method of the tracker. It returns whether an object that was
queried from the database at a given time is the current version of the object
or not. Implementation note: Currently empty session infos are returned,
this may later change, if session infos will be also kept track of.
A SessionInfo object if the object is not current. The session infomay contain the last modification transaction's info, but this is not guaranteed. |
