Openlayers 实现撤消特征修改

Question

I'm using openlayers,

Already I can set feature structure by using modify

and now trying to reset feature structure to the first structure, before modify.

I guess I need to save geometry coordinates before modify
and then setGeometry by the saved geometry coordinates when click on undo;
