committingTransaction
Called by aCDOTransactionbefore 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
Called by aCDOTransactionafter 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
Called by aCDOTransactionafter 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.
