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.

Variables

		Name	Description
	TArray< int32 >	Indices
	TArray< ValueTy...	NewValues
	TArray< ValueTy...	OldValues

Overridden from FChange

	Name	Description
void	Apply ( UObject* Object )	Makes the change to the object
void	Revert ( UObject* Object )	Reverts change to the object
FString	ToString()	Describes this change (for debugging)
