ActionDeltaItem Class Reference

Detailed Description

The ActionDeltaItem object tracks changes made on a parameter that is part of a reference model. Each ActionDeltaItem represents a single change, or modification, to a referenced parameter. So each time there a change to a static value, an FCurve, a Constraint, an Expression or a GroupRelation, a new ActionDeltaItem is generated.

You can also create new ActionDeltaItems from a data set using one of these functions:

ActionDeltaItem objects of the same type (see siModificationDeltaType) are stored in an ActionDelta which is accessible via the ActionDelta::GetItems function.

Since:
6.0
Example:
