public interface TransactionOperations
TransactionTemplate. Not often used directly, but a useful option to enhance testability, as it can easily be mocked or stubbed.
<T> T execute(TransactionCallback<T> action) throws TransactionException
Allows for returning a result object created within the transaction, that is, a domain object or a collection of domain objects. A RuntimeException thrown by the callback is treated as a fatal exception that enforces a rollback. Such an exception gets propagated to the caller of the template.
