Detailed Description

Class for mapping between an index and an attribute data offset.

GA_AIFEditDelta objects store element deltas by an ordered index, not necessarily corresponding to the element's order in an GA_IndexMap. This class maps between that index and the corresponding data offset in a particular attribute.

The simplest map is to use the ordered index from a GA_IndexMap as the delta index. TODO: Add a virtual getDeltaIndexTraverser which yields data offsets in delta index order. This may be more efficient for GA_AIFEditDelta::apply
