- Method Detail
  - committingTransaction
```
void committingTransaction(CDOTransaction transaction,
                           CDOCommitContext commitContext)
```
    Called by a CDOTransaction before it is being committed. The implementor of this method is allowed to throw an unchecked exception that will propagate up to the operation that is about to commit the transaction (thereby preventing the operation from completing successfully). The implementor of this method is allowed to apply changes to the object graph managed by the transaction.
  - committedTransaction
```
void committedTransaction(CDOTransaction transaction,
                          CDOCommitContext commitContext)
```
    Called by a CDOTransaction after it is being committed. The implementor of this method is not allowed to throw an unchecked exception.
    If you're interested in the results of the commit operation consider to implement CDOTransactionHandler3.committedTransaction().
  - rolledBackTransaction
```
void rolledBackTransaction(CDOTransaction transaction)
```
    Called by a CDOTransaction after it is rolled back. If the implementor of this method throws an exception it will be logged as an error and subsequent handlers will be further called.
