TransactionCallback (ebean api 12.8.0 API)

All Known Implementing Classes:

TransactionCallbackAdapter
```
public interface TransactionCallback
```
Provides a callback that can be registered with a Transaction.
The callback methods are called just prior to and after the transaction performs a commit or rollback.
A typical use of TransactionCallback would be to clean up non-transactional resources like files. For example, when processing files on postCommit/postRollback clean up the associated files. As another example when on postCommit of a delete remove associated resources from the file system or remote service.
