TransactionalComponentByLock (Apache Jena - DBOE Transactions 4.1.0)

java.lang.Object
- org.apache.jena.dboe.transaction.txn.TransactionalComponentLifecycle<java.lang.Object>
- - org.apache.jena.dboe.transaction.txn.TransactionalComponentByLock

All Implemented Interfaces:

TransactionalComponent
```
public class TransactionalComponentByLock
extends TransactionalComponentLifecycle<java.lang.Object>
```
Implementation of the component interface for TransactionalComponent. Useful for in-memory transactions that do not provide durability or abort (undo). When retro fitting to other systems, that may be the best that can be done.
