TDF_AttributeDelta (const Handle< TDF_Attribute > &anAttribute) | |
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.
