Syntax

template<typename ValueType>  
class TIndexedValuesChange : public FToolCommandChange

Remarks

TIndexedValuesChange stores a change of values at a set of indices. For example if you were changing positions of vertices of a mesh, you could use this change to store the new and old positions.

This is an abstract base class, you must provide suitable Apply/Revert implementations. The TCustomIndexedValuesChange subclass will allow you to do this with lambdas.
