PlatformTransactionManagerinterface, exposing a method for executing a given callback within a transaction.
Implementors of this interface automatically express a preference for
callbacks over programmatic
rollback calls. Calling code may check whether a given
transaction manager implements this interface to choose to prepare a
callback instead of explicit transaction demarcation control.
execute@Nullable <T> T execute
(@Nullable TransactionDefinition definition, TransactionCallback<T> callback) throws TransactionExceptionExecute the action specified by the given callback object within a transaction.
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.
