Class Overview
Callback interface for transactional code. Used with TransactionTemplate's
execute method, often as anonymous class within a method implementation.
Typically used to assemble various calls to transaction-unaware data access
services into a higher-level service method with transaction demarcation. As an
alternative, consider the use of declarative transaction demarcation (e.g. through
Spring's Transactional annotation).

Public Methods
public abstract T doInTransaction (TransactionStatus status)
Gets called by execute(TransactionCallback within a transactional context.
Does not need to care about transactions itself, although it can retrieve
and influence the status of the current transaction via the given status
object, e.g. setting rollback-only.
Allows for returning a result object created within the transaction, i.e. a domain object or a collection of domain objects. A RuntimeException thrown by the callback is treated as application exception that enforces a rollback. An exception gets propagated to the caller of the template.
Parameters
| status | associated transaction status |

- a result object, or
