This interface is a tagging interface for items that wants to
be notified before a transaction is committed or after it
has been completed or rollbacked. One example is the
File
item,
which must handle physical files on disk and check quota information. If a
file has been uploaded when a transaction is rolled back the file should also
be deleted. On the other hand, if a file item is deleted, the physical file
should not be deleted before DbControl.commit()
is called.
By implementing this interface an item tells the DbControl
to call the BasicItem.onBeforeCommit(Transactional.Action)
,
BasicItem.onAfterCommit(Transactional.Action)
or
BasicItem.onRollback(Transactional.Action)
methods, whenever
a commit is called or a rollback is required.
