Undoable C++ Object Library - multi-level undo and transaction rollback

This C++ library implements an object-oriented approach for reversing transactions at the C++ object level. A transaction consists of a series of three types of operations on objects: creation, modification, and deletion. The reversal (undo) of the transaction is implemented by effectively deleting the originally created objects, restoring the state of the modified objects, and effectively re-creating the deleted objects. References between objects are properly restored. This approach can significantly reduce the cost of implementing multiple level undo in an application, compared to a ! procedural "reverse transaction" approach. Object level undo also supports transaction rollback in other scenarios such as caught C++ exceptions.

The $495 product includes a 100-page tutorial and over 300 pages of documentation in helpfile and printed format. A free demonstration version of the library can be downloaded from the Web site listed below.
