TDF_AttributeDelta Class Reference

This class discribes the services we need to
implement Delta and Undo/Redo services.

AttributeDeltas are applied in an unpredictable
order. But by the redefinition of the method
IsNowApplicable, a condition can be verified
before application. If the AttributeDelta is not
yet applicable, it is put at the end of the
AttributeDelta list, to be treated later. If a
dead lock if found on the list, the
AttributeDeltas are forced to be applied in an
unpredictable order.
