TDF_Transaction Class Reference

This class offers services to open, commit or
abort a transaction in a more secure way than
using Data from TDF. If you forget to close a
transaction, it will be automaticaly aborted at
the destruction of this object, at the closure of
its scope.

In case of catching errors, the effect will be the
same: aborting transactions until the good current
one.
