Method Details

createSnapshot

protected Long createSnapshot()

Description copied from class: SnapshotJournal

Returns a new object containing a copy of this journal's current state.

One may settle for a partial copy of this journal's state, as long as the returned snapshot will be sufficient to rollback (via SnapshotJournal.revertToSnapshot(T)) all changes made to this journal's state since the snapshot was created.

SnapshotJournal.isInTransaction() will return true inside this callback, and will continue to return true until all snapshots have either been reverted to or committed.

Specified by:

createSnapshot in class SnapshotJournal<Long>

Returns:

a new object containing a copy of this journal's current state

revertToSnapshot

protected void revertToSnapshot(Long snapshot)

Description copied from class: SnapshotJournal

Rolls back to a state previously created by SnapshotJournal.createSnapshot().
