Detailed Description

template<class Key, class T>
class MyMoneyMap< Key, T >

Author:

Thomas Baumgart

This template class adds transaction security to the QMap<> class. The interface is very simple. Before you perform any changes, you have to call the startTransaction() method. Then you can use the insert(), modify() and remove() methods to modify the map. Changes are recorded and if you are finished, use the commitTransaction() to finish the transaction. If you want to go back before you have committed the transaction, use rollbackTransaction() to set the container to the state it was in before you called startTransaction().

The implementation is based on the command pattern, in case someone is interested.
