## Methodendetails

### 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.
