Package org.aksw.commons.txn.impl

Interface TxnHandler

All Known Implementing Classes:
TxnHandlerImpl
public interface TxnHandler
Callbacks for reacting to events during the life cycle management of transactions. The most relevant callback is beforeUnlock(Path, boolean): At this point resources have been written and are in their final location but the lock is still held. This allows one to e.g. safely read the last modified timestamp of a just committed file before another transaction can modify it again.
