- All Implemented Interfaces:
    TransactionCallback<Object>

      public abstract class TransactionCallbackWithoutResult
      extends Object
      implements TransactionCallback<Object>

  Simple convenience class for TransactionCallback implementation. Allows for implementing a doInTransaction version without result, i.e. without the need for a return statement.

      Description copied from interface: `TransactionCallback`
      Gets called by `TransactionTemplate.execute(org.springframework.transaction.support.TransactionCallback<T>)` 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. Any such exception will be propagated to the caller of the template, unless there is a problem rolling back, in which case a TransactionException will be thrown.

      Specified by:
        `doInTransaction` in interface `TransactionCallback<Object>`
      Parameters:
        `status` - associated transaction status
      Returns:
        a result object, or `null`

    - #### doInTransactionWithoutResult

          protected abstract void doInTransactionWithoutResult(TransactionStatus status)

      Gets called by `TransactionTemplate.execute` 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.

      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.

      Note when using JTA: JTA transactions only work with transactional JNDI resources, so implementations need to use such resources if they want transaction support.

      Parameters:
        `status` - associated transaction status
