DBtransactionRollback

Declining make to a change.

Moskito puts in to every Workfile *.wf a transaction log *.tr. In this file all changes in the Workfile are carried along. As soon as a transaction is finished, the log file is physically written. After successful securing of the Workfiles at the end of a Moskito's meeting the log file is removed. If Moskito hits by the start on an available log file, Moskito has broken off before. And the Workfileinhalt is reconstructed with the help of the last valid transaction. Every transaction can be cancelled about access functions and be restored.

With this function an implementation can be cancelled, but only if it was also taken down.
